Homonyms, Etymologically Speaking: X

Many words have two meanings, sometimes more, which are often very different. Such words have identical spelling and pronunciation, they are known as homonyms. Here I continue an A to Z list of such words and look at how that word came to have two different meanings.

X is for x ..... well it isn't for anything as there isn't a single homonym beginning with that letter. So let's have some fun with etymologies of words beginning with X and we will begin with....

Xenon, a gas named in 1898 by Scottish chemist Sir William Ramsay from the Greek word xenon meaning 'foreign, strange' and coming from the Proto-Indo-European root ghos-ti 'stranger, guest, host'.

Xylem is named from the German xylem and the Greek xylon 'wood'. It is the woody tissue found in the most evolved of plant life.

Xerox, the trademark name of a copying device, it held by Haloid Co, of Rochester, New York State. It comes from xerography, defined as 'photographic reproduction without liquid developers'. In 1965 the word became listed in the dictionary as a verb meaning 'to produce using a copier', and while the company strongly objected to inclusion in the dictionary, thus making it acceptable, they were ultimately unsuccessful.

Homonyms, Etymologically Speaking: W

Many words have two meanings, sometimes more, which are often very different. Such words have identical spelling and pronunciation, they are known as homonyms. Here I continue an A to Z list of such words and look at how that word came to have two different meanings.

W is for watch, be it the timepiece or simply to observe. The latter is seen in Old English waecce 'state of being awake'; from Proto-Germanic wakjan and Proto-Indo-European weg 'be strong, lively'. Hence watchfulness and awake are ostensibly the same thing.

The timepiece is seen from 1580, and was a device to waken sleepers who would then be 'on watch' in the next crew rotation.

Homonyms, Etymologically Speaking: R

Many words have two meanings, sometimes more, which are often very different. Such words have identical spelling and pronunciation, they are known as homonyms. Here I continue an A to Z list of such words and look at how that word came to have two different meanings.

R is for right, which is either correct, the opposite of left, or morally correct. All three have a common root in Proto-Indo-European reg, meaning 'move in a straight line'. The first is the reason we still say that someone honest (or right) is straight; the second is simply a reflection on how the majority of people are right-handed, those left-handed were seen as suspicious (or worse) for much of history; and the moral right is the same as the correct right.

Homonyms, Etymologically Speaking: F

Many words have two meanings, sometimes more, which are often very different. Such words have identical spelling and pronunciation, they are known as homonyms. Here I continue an A to Z list of such words and look at how that word came to have two different meanings.

F is for file, and one my favourite words when it comes to its usage over the years. Likely our first thought turns to the tool used to smooth or abrade, this comes from the Proto-Germanic fihalo 'a cutting tool', and traceable to Proto-Indo-European peig 'to cut, mark by incision'. The second use, that heard so often in offices, refers to a place where documents are stored - even in the digital age the terminology has not changed - and has been derived from the first sense. How? Because the original filing systems were not drawers, but a length of wire produced by a cutting-like process. The papers would be suspended from the wire or file until required. We still remember those days because we never spoke of the document being in the drawer as being 'in file' but always 'on file'. This is why etymology and the development of language is fascinating.

Homonyms, Etymologically Speaking: E

Many words have two meanings, sometimes more, which are often very different. Such words have identical spelling and pronunciation, they are known as homonyms. Here I continue an A to Z list of such words and look at how that word came to have two different meanings.

E is for even, used to mean 'equal' and also as a comparison such as in the phrase 'even when'. The etymological trail for the former begins with Old English efen, similar forms seen across the range of Germanic languages suggest earlier forms will have seen little change but unfortunately no trace of such has ever been found. The second sense, to liken, compare, is unrecorded before the 13th century and thus will have come from the adjective.

There was once a third use, from Old English aefen 'at the end of the day'. This is not related to the other words but is akin to 'eve' and 'evening'. It also reminds us that while today the day ends at midnight, once the day ended when the sun went down - which makes far more sense. Expressions featuring 'even' include: even break first appears in print in 1907; even-steven, first seen in 1866; to get even with is from 1833; and even-tempered from 1712. There are also a couple of expressions which have fallen out of use: even-old 'of the same age'; and even-sucker meaning 'foster-brother'.

Homonyms, Etymologically Speaking: C

Many words have two meanings, sometimes more, which are often very different. Such words have identical spelling and pronunciation, they are known as homonyms. Here I continue an A to Z list of such words and look at how that word came to have two different meanings.

C is for cross, as in 'angry' and the name of the best-known Christian image. The latter came first, derived from 'across' in the sense of 'going across the grain' or 'across the main flow' or simply 'intersecting'. This can be traced back, and through any number of languages, back to Latin crux with the same meaning. Having learned the early meanings, it is easy to see why someone not conforming or agreeing with another would be seen as 'cross' in that sense and, at least etymologically speaking, both words have a common root.

Homonyms, Etymologically Speaking: B

Many words have two meanings, sometimes more, which are often very different. Such words have identical spelling and pronunciation, they are known as homonyms. Here I continue an A to Z list of such words and look at how that word came to have two different meanings.

B is for band and also for bat. Taking 'band' first, clearly the earliest usage would have been as in the sense 'a flat strip, that which binds'. This word is seen in Old English bend, Old Scandinavian band, and Old French bande, and all with identical meanings. Clearly this monosyllabic word has been around a long time, and we can trace it back to the root word bhendh, meaning 'to bind' in Proto-Indo-European.

The second use of 'band' is as in the sense 'an organised group', particularly used when speaking of an armed group of men. It is not difficult to see how the 'binding' of a flat strip has been transferred to the 'binding together' of a group of individuals. This is also why a group of musicians are known as a 'band', and has been since at least 1660.

An examination of 'bat' looks at both the flying mammal and that used to hit a ball (or similar) in sporting contests. Taking the latter first, Old English batt was used to refer to a cudgel, and was a loan word from Irish bat and Gaelic bata, both having identical meanings. These come from the Proto-Indo-European bhat 'to strike'. Note the Middle English use referred to a 'lump, piece, chunk', the term surviving in terms such as 'brickbat'.

When it comes to the mammal, the creature was known in Middle English as bakke, this related to Old Swedish natbakka 'night bat', and Old Norse ledrblaka which might be used to mean 'bat' but literally translates as 'leather flapper'. This is also seen in the Proto-Indo-European bhlag 'to strike', this also the origin of words such as 'flagellate'. Old English hreremus was also used to refer to a bat, this from hreran 'to shake'.

Etymologies and Homonyms (again)

Whilst I am always interested in learning new words, it is the never so much the meaning as the origins which intrigue me. A couple of years ago I looked at homonyms, a word with two meanings and I looked at the etymologies of these words. Were there two completely different origins and the identical spelling is pure coincidence or has the word simply been used to mean two different things?

Here are another selection and, having done ABC before, now continue with a selection of others:

Dear can be used as a noun to mean ''beloved' and as a verb to mean 'expensive'. In both cases this is from the Old English deore and if defined as 'precious' can also be used in both senses.

Deck can be used to mean 'adorn' and also to refer to a part of a ship. Both are derived from Middle Dutch dekken meaning 'to cover' and, once again, appropriate to both senses. Note the use referring to a pack of cards is first seen in the late 16th century, thought to liken the stacked cards as the decks of a ship. Later use as a tape deck, coined around 1949, describes the flat surface required to ensure smooth passage of the recording tape from one reel to another.

Down is also used to describe soft feathers as well as the opposite of up. These have to quite different origins, albeit from similar words. Old English dun meant 'hill', still seen in the similar modern word 'dune', today only used to refer to sand features. We also find Old Scandinavian dunn referring to 'soft feathers', this derived from Proto-Indo-European dheu which referred to 'to fly (like dust)' or 'rising cloud'.

Duck is found in its earliest form as a verb. Germanic languages feature intermediate forms - Old High German tuhhan, German tauchen, Old Frisian duka, Middle Dutch duken, and Dutch duiken - are come from Proto-Germanic dukjan or 'to plunge or dive'. As a noun it is easy to see how dabbling is why the waterfowl earned this name. Furthermore because the females greatly outnumber the males, this is why the females are known generically as 'ducks' while males are specifically 'drakes'. The use of 'duck' as a noun is a late addition to Old English, Saxons used the term ened from Proto-Indo-European aneti.

Even can be used to mean 'alike' as well as 'equal'. The latter is from Old English efnan with the former from the similar efen. Both undoubtedly have the same root, although when the two meanings first came about has never been identified and by the same token we have no idea which use came first.

Exact is most often used as an adjective meaning 'precise'. This is from the Latin exactus, with the same meaning, itself the past participle of exigere which means 'demand, enforce' and is also how the word 'exact' is used as a verb. In English the 'demand' meaning is much older than the more common modern use of 'precise'.

Fawn is most often used to refer to the young of the deer and, as with the previous example, is of later origin than the verb. The young deer came to English from Old French feon which originally meant 'young animal' rather than specifically 'young deer', indeed the former was in popular use until at least the 15th century in England, too. This ultimately shares an origin with 'foetus', the Latin fetus meaning 'bringing forth' as well as 'offspring'. When it comes to the verb meaning 'grovel', this began as Old English faegnian or 'rejoice, applaud'. Later Middle English used 'fawn' as an expression of great pleasure and delight, in particular we find it used most often in reference to a dog wagging its tail.

File can be used to refer to the tool or the act of using said tool to smooth or abrade, particularly in metalwork. In this sense Old English feol comes from Proto-Germanic fihalo 'cutting tool' and Proto-Indo-European peig 'to mark by cutting, an incision'. Interestingly a couple of Eastern European languages have also evolved this root to mean 'paint', presumably both are linked in the sense of the piece being improved upon by work done on it. Talking about a file in the office sense (computer terminology simply borrowing this usage), has a strange etymology indeed. First seen in the early 16th century, this is from the Old French file meaning 'a row' and still used in English in this sense. The link from 'a row' to 'documentation' is through the original filing being done by stringing the documents on a cord or wire. This is reason we so often hear administrative excuses telling us something is either 'on file' or, more often, 'not on file'.

Fine has three uses: as an adjective meaning 'pure, refined'; to describe something as 'delicate'; and as a verb meaning 'penalise'. The first example is from Old French fin 'perfected', itself sharing a root with 'finish' and the French word finis. In Modern French the word continues to be used in the second sense of 'delicate', and came to English in a general sense around 1300 when used to express approval, this is why we use expressions such as 'fine figure' and 'fine arts'. When it comes to third meaning, this is also Old French where fin was used to mean 'limit, death, boundary' as well as in the sense 'fee, payment, finance, money', the different uses probably beginning as when a debt became due, ie the period of credit had come to an end.

Fire could well be one of the earliest words ever spoken, or at least one of the earliest ever described. Clearly that original sense referred to flame and, while we will never know what language was first spoken, we do know a reasonable amount of Proto-Indo-European, the root of most European and related languages. This ancient tongue appears to have to quite different roots for 'fire': this seen in paewr which should be seen as 'inanimate' and probably best seen as the chemical process and thus the process of burning; and also from egni, the origin of 'ignite' and used in the sense of 'animate', ie the living flame. Fascinatingly the latter 'animated' use is also seen in viewing water as a 'living force' both etymologically as well as elementally. When used to mean use of a gun, this undoubtedly refers to the flame associated with early musketry and although we use 'fire' with archery today, this is a modern term and Saxon archers would have said 'shoot'. The ejection of the projectile in guns, muskets and canon is undoubtedly the reason for using fire to mean 'dismissal', this not seen before 1885.

Flat has three uses today. The earliest, and most obvious, came to English from Proto-Germanic flata which meant 'shallow' as well as 'flat'. It is worth noting that while today we would see 'flat' as meaning 'having no significant rises', the original sense was 'having no significant dips'. The use of 'flat' to refer to a property on a single storey began some two centuries ago in Scotland and originally described (quite sensibly) what we would today see as a bungalow. It is derived from a source meaning 'ground, floor' and ultimately used to refer to 'level ground near water'. In a musical sense it is first seen in the late 16th century, this originally being used to mean 'dull, featureless, lacking contrast' - we still speak of 'featureless' when looking across a flat landscape. Around the same time, indeed within ten years either side, we find 'flat' used in the context of 'unexciting' and also in reference to drink being flat.

Fold is used as a noun to refer to an enclosure for animals, this from a Germanic root and brought to England by the Saxons with falud. While evolution of the word is uncertain, it is interesting to note the Dutch vaalt and East Frisian folt have the same origins but have come to mean 'dunghill'. As a verb the history is much clearer. Distributed across the northern hemisphere and seen in Albanian pale, Greek ploos, Latin plus, and Sanskrit putah, while also evolving in some languages to mean 'a joint'.

Etymologies and Homonyms

Whilst I am always interested in learning new words, it is the never so much the meaning as the origins which intrigue me. Overhearing a conversation where one learned there were two meanings for one word made me think about the etymologies, the origins of the word. Were there two completely different origins and the identical spelling is pure coincidence or has the word simply been used to mean two different things?

I took a look at a number of examples and discovered the following:

Address: as a verb to mean 'to guide or direct', it came to English in the 14th century from Old French adrecier meaning 'straighten, set right' and from Latin addirectaire with the same meaning. When it comes to the noun and meaning 'dutiful or courteous approach' it is first seen in the 1530s and is derived from the verb. As a noun the sense of 'formal speech' dates from the 1750s and in referring to a place of residence is not known prior to 1888.

Arm: when referring to the upper limb the word can be traced back to Proto-Germanic armaz and Sanskrit irmah and has probably remained largely unchanged since the development of Proto-Indo-European. Note, however, the later change in languages such as Greek arthron 'a joint', Latin armus 'shoulder', and Armenian armukn 'elbow'. In the sense of 'a weapon' it can be traced to Proto-Indo-European ar 'fit, join' and eventually used as a verb.

Bank:as a financial institution dates from the 15th century and originated in the Italian banca meaning 'table', coming to English through Middle French banque with the same meaning. Whilst unrecorded this almost certainly came from the Germanic for a 'bench'. The second use is for the slope or a bank of earth. This certainly came to English from the Proto-Germanic bangkon meaning 'slope' and having a common origin with bankiz or 'shelf'. Hence the word, despite having two quite diverse uses, has the same source in the early European tongues but by coming to English through very different routes has two quite different meanings.

Bark: when referring to the sound made by a dog, is from Proto-Germanic berkan and simply imitative of the sound. When it comes to the noun describing the covering on the trunk of a tree, the term most likely came to English from Old Norse barkr and from Proto-Germanic barkuz and seem certain to be from the name of the birch tree.

Base: when used as a verb or noun to refer to a low point or foundation, it is surprisingly recent and not seen before the 14th century as a noun and in 1841 as a verb. Both are derived from Old French bas 'depth', Latin basis and Greek basis 'foundation, step'. Also used as an adjective meaning 'lowly', this has exactly the same origins.

Beam: in the modern sense would refer to rays of light and seen since the 15th century. (Smiles and radio transmissions being derived from the same source.) Also used today to refer to wooden beams used for construction purposes, this originally referred to the 'living tree' and ultimately comes from Proto-Indo-European bheue simply meaning 'to grow'.

Board: when referring to 'a plank' it can be traced to Proto-Germanic burdam and ultimately Proto-Indo-European bhrdh both with identical meaning and thus likely one of the earliest words coined. Interestingly there is also a Proto-Indo-European bherdh, almost the same word but used in the sense 'to cut', further evidence of this being among the first key words used by the people of the European continent. The word 'board' has a number of other meanings - including 'to get onto', 'food and lodging' - are both derived from the original 'plank' meaning. In the case of the 'food and lodging' meaning, this comes from the use of a 'board' as a table top, a board not fastened down but simply resting on the trestle below - one side polished and on which the food was served, the reverse scrubbed clean but left in its natural state on which the food was prepared.

Bolt: as a verb used, in a general sense, to mean 'move rapidly' in its various forms is seen from the 13th century and undoubtedly comes from the bolt or arrow used in a crossbow. The stout arrow known as a 'bolt' is ultimately from Proto-Indo-European bheld or 'to knock or strike'.

Bow: when used to refer to the weapon used to fire an arrow comes from a Proto-Germanic bugon with the same meaning. The reference to a looped knot is seen from the middle of the 16th century and speaks of it being shaped like the weapon.

Box: the noun referring to the wooden container is probably from the Greek where pyxis refers to a box made from boxwood', while the Greek for 'the box tree' is pyxos. When it comes to 'box' being used in the sense of 'a blow' the origin is much later and completely unrelated. Traceable only as far as the 13th century, it can be found in the Middle Dutch boke and Middle High German buc, likely imitative of the sound.

Can: as the 1st and 3rd person singular of 'know', the origin of which is Proto-Indo-European gno, has its vowel change through influence from other early European languages such as Old Frisian kanna and Proto-Germanic kunnan.. In the sense of a 'container' the origins are uncertain but came to English from Proto-Germanic kanna and seen in Late Latin canna with the same meaning and early Latin canna 'reed pipe, boat'.

Cast: began as meaning 'to throw' and came from Old Norse kasta, every other usage came from here - including 'group of actors', 'an eye condition', 'turn', 'a shape from molten metal'.

Chip: in the sense 'piece of wood' can be traced to Proto-Indo-European keipo 'sharp post' and eventually came to mean 'small piece of wood' in Dutch kip and smiliar. The later use to mean 'that cut off' has clear connections and first seen in the early 15th century.

Clear: as a verb and as an adjective - be it to tidy, prove innocent, explain and a number of others - seen since the 13th century and new uses can be found up to the end of the 19th century. The many uses indicate several sources from other languages and there are a number of cases of influence from other languages where the meaning is somewhat different: Old French cler 'bright, shining', Latin clarus 'clear, loud', Italian chiaro and Spanish claro 'illustrious, famous, glorious'. All these can be traced to Proto-Indo-European kle meaning 'to shout'.

Club: used as a noun to mean 'a gathering, an association', is first known in a document from the early 17th century. In the late 13th century we first find the use as 'sizable stick used as a weapon', this from the Old Norse klubba meaning 'cudgel'. Note the suit in playing cards is unknown prior to the 17th century, earlier it being known by its Spanish or Italian names of basto and bastone respectively. By the 17th century the shape shown was that of the trefoil, Danish klover and Dutch klaver literally 'a club at cards' but clearly related to the English 'clover'.

Current: is first applied to the flow of electrical force in 1747, this obviously taken from the flow of water and derived from Old French corant meaning 'running, lively, eager, swift' and from Latin currere 'to run', itself from Proto-Indo-European kers 'to run'. It has been used to mean 'the present time' since around 1570 and should be seen as using 'running' in the same sense as when we speak of something currently being shown.

An A-Z of Homonyms (Almost)

While working on my last post I was reminded of a question posed to me at a recent talk. Specifically a member of Stone Historical and Civic Society asked about the use and origins of the word ‘plant’ when speaking of heavy machinery. Did it have an entirely different etymology to its more common use? Of course at that moment I had absolutely no notion. However I did promise to cover such in my blog and here it is.

Any word having the same spelling and pronunciation but having more than one meaning is described as a homonym. Correctly these should be seen as different words for, as we shall see, they have rather different histories. When contemplating this post I had wondered just how many examples I could discuss and whether there would be enough to make it worthwhile. I will admit to being a little surprised by just how many there are and hence have opted for a simple alphabetical list. No apologies for omitting the letters X and Z for there are no homonyms beginning with these two letters – unless you can show me otherwise.

Ash – referring to the tree and also the residue from a fire. Doubtless one of the oldest words as it is one of the simplest sounds and an examination shows this to be true. Related to Greek azein ‘to parch’, to Latin ardus ‘dry’, and even Sanskrit asah ‘ashes, dust’. All have the common root of Proto-Indo-European ai meaning ‘to burn, glow’ and what was originally a reference to the fire later used in a plural form to give the modern meaning. When it comes to the tree, as with many tree names, it is the use of the wood we should look to. Ash was used to make the shafts of spears, indeed Old English aesc referred to both the tree and the spear, and comes from Proto-Indo-European root os for the ‘ash tree’. Over millennia this gave Old Norse askr, Dutch esce, German esche, Armenian haci, Latin ornus, Russian jasen, and Lithuanian uosis.

Bank – either the financial institution or used topographically. Clearly the latter will have been known and described thousands of years before even the concept of finance existed. However from an etymological perspective there is virtually no difference in the two. Both are known from around the thirteenth to fifteenth centuries and both seem to be derived from an unknown Proto-Indo-European word meaning something akin to ‘build up’, ascend’. The modern words have been derived from Old Italian banca ‘table’, in the case of the financial institute, and early Germanic bankiz or ‘bench’, when speaking of a feature in the landscape.

Carp – is either a fish or to complain. The piscine form is by far the simplest, ultimately from an East Germanic karpa and the name given to a fish found in the Danube. Once the carp was prized as a food fish, indeed this was the reason for the creation of the many fish ponds into which these fish were introduced – they satisfied the need for protein in a diet, especially when religion deemed it wrong to eat red meat on Fridays. We do not know the original use of the word, however anything other than a reference to food is highly improbable. When it comes to the use of ‘complaint’, the word comes to English from Latin carpere ‘to slander, revile’ and ultimately from Proto-Indo-European kerp meaning ‘gather, pluck, harvest’. Hence the phrase ‘to pick or pull apart’, as in an argument, has the identical origin and ‘carp’ in this sense shares an origin with ‘harvest’.

Dock – as in a place where craft come to be unloaded or in the sense to remove the tail of an animal. The former appears to have been used initially to refer to a rut created by the passage of a wheel through wet or muddy ground. As a dock is a man-made feature, the cutting to where the goods can be unloaded would resemble the wheel rut. To remove part of an animal’s tail is first used in the late fourteenth century, ultimately this comes from Proto-Germanic dokko meaning ‘a bundle’ or ‘something round’ and its use for a shortened tail a reference to the muscle which had been cut.

Egg – the obvious reproductive reference is ultimately from Proto-Indo-European awi meaning ‘bird’. When it comes to meaning ‘to incite’, it comes to English from Old Norse eggja and from ‘edge’ as in ‘to advance slowly’ and thus misunderstood pronunciation.

Firm – meaning ‘solid, stable’ and another word for a company or business. The former is ultimately from Proto-Indo-European dher ‘to hold, support’ and evolved before coming to English through the Latin firmus ‘strong, steadfast’. When used in the business sense the origin is also Latin but here from firmare or ‘to sign’, this giving us the modern ‘affirmation’ in the same sense.

Gum – can be a part of the mouth where the teeth erupt or an adhesive. In the latter the use can be traced to Latin gumma, Greek kommi and Egyptian kemai, all meaning ‘resin’ and used in this sense to refer to texture. When it comes to a part of the mouth we can trace it back to gheu, the Proto-Indo-European word meaning ‘to yawn’. Later we find Lithuanian gomurys, Old High German goumo, and Old Norse gomi, all meaning ‘palate’.

Hail – used to describe frozen rain and to refer to a greeting. The latter was first used as a nautical greeting, first seen in print in the sixteenth century, and from the religious salutation Hail Mary or ave Maria. Weather-wise it is related to Greek kakhlex ‘round pebble’ and ultimately from Proto-Indo-European kaghlo ‘pebble’.

Inch – as in the imperial measurement and also a small Scottish island. The former comes from the Latin root uncial meaning ‘a twelfth part’. The island is much earlier and seen in Gaelic innis, Old Irish inis, Welsh ynys, and Breton enez, all from the earliest meaning of ‘land by a river’.

Jade – used for the ornamental stone and also in ‘to weary’ and possibly my favourite homonym, at least from the etymologies. The stone can be traced back to Latin ilia meaning ‘flanks, kidney area’. It came to English through Spanish piedra de la ljada around the sixteenth century to mean ‘pain in the side’ or ‘stone of the colic’. It was thought jade could cure such an ailment. Its use meaning ‘to tire’ seems to be from the earlier noun referring to ‘a worn-out horse’ – and was also once used as a derogatory term for a woman.

Key – either that used to open a lock or a musical reference. The former is of uncertain etymology but thought to come from the Proto-Germanic ki meaning ‘to cleaver, split’. Musically the reference is from Latin clavis and French clef and thought to come from a reference to ‘the lowest note on the scale’.

Lark – either the bird or meaning ‘a prank’. The latter has been suggested as coming from ‘skylark’, a nautical reference to the play of sailors in the rigging likened to that of the singing of the skylark – hence ‘larking about’. As for the bird the modern etymology is all we have, although some sources suggest a compound of Norse and Saxon referring to a ‘treason-worker’, the reason for which is unexplained.

Mace – is either a weapon or a spice. The weapon is ultimately from the Latin matteola or ‘type of mallet’. The spice is less certain but may be related to Latin macir, this the name of an Indian spice obtained from the bark of a tree, although this is disputed.

Nap – can be a short sleep, or a reference to the smooth surface of cloth. The sleep is known in earlier tongues, such as Old High German hnaffezan and Norwegian napp, yet with identical meaning the source is unclear. Of course it is always possible that ‘nap’ was the original word for ‘sleep’, certainly the latter has no very earlier references. When it comes to cloth the term comes from a root giving Old Swedish niupa and Gothic dis-hniupan ‘to tear, and a description of removing anything from the cloth which would spoil the finish.

Ounce – and when it comes to the imperial measurement of weight is ultimately from Latin uncial ‘one-twelfth’ and thus sharing an origin with ‘inch’. Of course there are 16 ounces to the pound in the avoirdupois system, this refers to the Troy system of weights. Note the abbreviation oz is from Italian onza. The ounce is also an alternative name for the snow leopard, this comes from the Old French word lonce, originally referring to the lynx.

Plant – was the original question posed and can refer to either flora or to heavy machinery. The more common usage is clearly the oldest for plants were plants before the Industrial Revolution. Whether used as a noun or verb the origin is Proto-Indo-European plat meaning ‘to spread’ or ‘flat’ and clearly first a reference to where the plants were planted, literally ‘a place’. In its modern sense it is not seen before the sixteenth century. In the machinery sense it is first recorded in a document dated 1789, where the reference is to where something had been constructed for industrial purposes, literally the machinery had been placed or planted.

Quack – used to refer to the sound made be a duck and a medical figure of dubious qualifications. Taking the anseriformes first, the sound can be traced back through Middle Dutch quacken to the Latin coaxare ‘croak’, and Greek koax meaning ‘the croaking of frogs’, and Hittite akuwakuwash ‘frog’. In a medical sense it is short for ‘quacksalver’, a Dutch phrase ‘hawker of salve’ where salf meant ‘salve’, and originally used as ‘to play the quack’.

Race – either a reference to cultural heritage or to a speed contest. That meaning ‘of common descent’ is only seen from the sixteenth century, itself from Middle French razza meaning ‘lineage, family’ and first used in English to denote those with a common occupation. The predictably earlier use, although not by much, comes from Scandinavian rasen meaning ‘to rush’ is first seen in the thirteenth century.

Sage – is used to describe wisdom and is a herb. In the former we find Latin sapere ‘to have taste’ as well as ‘be wise’. This is from Proto-Indo-European sap ‘to taste’. As a herb it came to English from Old French sauge, itself from Latin salvia meaning ‘healthy’. Interestingly the English ‘safe’ has identical origins. The herb gets its name through usage, sage being used to clean teeth, ease soreness of the gums, and as a cure for arthritis.

Tender – either meaning ‘soft’ or ‘to offer’. The former comes to English through Old French and from Latin tenerem not only used for ‘soft, delicate’ but also ‘youthful’. Here Proto-Indo-European ten ‘stretch’ was used in the sense of ‘thin’ then ‘weak’ and finally ‘delicate’. The latter comes to English from tender Old French for ‘to offer’ and from Latin tendere ‘to stretch, extend’.

Utter – either ‘to speak’ or ‘absolute’. Sharing an origin with ‘out’ and from Proto-Indo-European ud which has the same ‘to put out’ meaning. The use of ‘to the utmost degree’ comes from Old English uterlic meaning ‘external’. Thus both have a loosely common root. Note ‘utter’ was also used until comparatively recently to mean ‘to release’.

Vault – is either a leap or a strong-room. The athletic reference is ultimately from Latin volvitare ‘to turn or leap’, coming to English through the Old French volter. The other origin is from an Old French vaulter referring to ‘an arched roof’. Today used more often as in a bank vault, the term originated as a reference to a vault in a crypt. Architecturally this referred to the arch.

Wax – is either used as a noun or as a verb. Originally wax was seen occurring naturally in honeycombs and thus Old English weax, Old Slavonic vosku, Polish wosk, Russian vosk and Proto-Indo-European wosko all referred to ‘that substance made by bees’. As a verb and meaning ‘to grow’, the term comes through Old English weaxen, Old High German wahsan, Old Norse vaxa, and Proto-Indo-European weg.

Yak – is either a wild Asian ox or a term meaning ‘to talk idly’. The former is first seen in Europe from the end of the eighteenth century and comes from Tibetan g-yag ‘a male yak’. Idle chatter was originally seen as ‘yack’, a term unheard before the twentieth century and having no etymological history to speak of.

Naturally many are monosyllabic, itself a reasonable, albeit general, explanation of why two words of different etymological beginnings and sources sound identical and consequently have the same spelling.
