Doublet (linguistics)

In etymology, '''doublets''' (alternatively '''etymological twins''' or '''twinlings''') are words in a given language that come from the same etymon. Doublets are often the result of loanwords being borrowed from other languages. While doublets may be synonyms, the characterization is usually reserved for words that have diverged significantly in meaning:<ref>{{cite book |chapter-url=//archive.org/stream/principlesofengl01skeauoft#page/414/mode/2up|first=Walter William|last=Skeat|author-link=Walter William Skeat|title=Principles of English Etymology: The Native Element|chapter=Doublets and Compounds|page=414ff §389–391, ''passim''}}</ref> for example, the English doublets ''pyre'' and ''fire'' are distinct terms with related meanings that both ultimately descend from the Proto-Indo-European (PIE) word {{lang|ine-x-proto|péh₂ur}}.

Words with similar meanings but subtle differences contribute to the richness of modern English, and many of these are doublets. A good example consists of the doublets ''frail'' and ''fragile''. (These are both ultimately from the Latin adjective {{lang|la|fragilis}}, but ''frail'' evolved naturally through its slowly changing forms in Old French and Middle English, whereas ''fragile'' is a learned borrowing directly from Latin in the 15th century.)

Another example of nearly synonymous doublets is ''aperture'' and ''overture'' (the commonality behind the meanings is "opening"). Doublets may also develop contrasting meanings, such as the terms ''host'' and ''guest'', which come from the same PIE word {{lang|ine-x-proto|gʰóstis}} and already existed as a doublet in Latin, and then Old French,<ref>''{{linktext|oste|lang=fro}}'' or ''{{linktext|hoste|lang=fro}}'' in Old French. {{Cite OED2|host, n.2}}</ref> before being borrowed into English. Doublets also vary with respect to how far their forms have diverged. For example, the connection between ''levy'' and ''levee'' is easy to guess, whereas the connection between ''sovereign'' and ''soprano'' is harder to guess.

==Origin== Doublets can develop in various ways, according to which route the two forms took from the origin to their current form. Complex, multi-step paths are possible, though in many cases groups of terms follow the same path. Simple paths are discussed below, with the simplest distinction being that doublets in a given language can have their root in the same language (or an ancestor), or may originate in a separate language.

===Native origin=== Most simply, a native word can at some point split into two distinct forms, staying within a single language, as with English ''too'' which split from ''to''.<ref>{{cite web|url=https://www.etymonline.com/word/too|title=too - Origin and meaning of too by Online Etymology Dictionary|website=www.etymonline.com}}</ref>

Alternatively, a word may be inherited from a parent language, and a cognate borrowed from a separate sister language. In other words, one route was direct inheritance, while the other route was inheritance followed by borrowing. In English this means one word inherited from a Germanic source, with, e.g., a Latinate cognate term borrowed from Latin or a Romance language. In English this is most common with words which can be traced back to Indo-European languages, which in many cases share the same proto-Indo-European root, such as Romance ''beef'' and Germanic ''cow''. However, in some cases the branching is more recent, dating only to proto-Germanic, not to PIE; many words of Germanic origin occur in French and other Latinate languages, and hence in some cases were both inherited by English (from proto-Germanic) and borrowed from French or another source – see List of English Latinates of Germanic origin. The forward linguistic path also reflects cultural and historical transactions; often the name of an animal comes from Germanic while the name of its cooked meat comes from Romance. Since English is unusual in that it borrowed heavily from two distinct branches of the same language family tree – Germanic and Latinate/Romance – it has a relatively high number of this latter type of etymological twin. See list of Germanic and Latinate equivalents in English for further examples and discussion.

Less commonly, a native word may be borrowed into a foreign language, then reborrowed back into the original language, existing alongside the original term. An English example is ''animation'' and ''anime'' "Japanese animation", which was reborrowed from Japanese {{lang|ja|アニメ}} ''{{lang|ja-Latn|anime}}''. Such a word is sometimes called a ''{{lang|de|Rückwanderer}}'' (German for "one who wanders back").<ref>{{cite web |title=Etymology: φλιτζάνι, fincan, فنجان |url=http://hoapp.com/thread-81754-1-1.html |website=Discuz! |access-date=6 November 2014 |date=2011-06-20 |quote=a wild guess — the Persian word pingân seems to suggest the form 'finjan' is a reloan from Arabic.

===Borrowed origin=== In case of twins of foreign origin, which consist of two borrowings (of related terms), one can distinguish if the borrowing is of a term and a descendant, or of two cognate terms (siblings).

Etymological twins are often a result of chronologically separate borrowing from a source language. In the case of English, this usually means once from French during the Norman invasion, and again later, after the word had evolved separately in French. An example of this is ''warranty'' and ''guarantee''.

Another possibility is borrowing from both a language and its daughter language. In English this is usually Latin and some other Romance language, particularly French – see Latin influence in English. The distinction between this and the previous is whether the source language has changed to a different language or not.

Less directly, a term may be borrowed both directly from a source language and indirectly via an intermediate language. In English this is most common in borrowings from Latin, and borrowings from French that are themselves from Latin; less commonly from Greek directly and through Latin.

In case of borrowing cognate terms, rather than descendants, most simply an existing doublet can be borrowed: two contemporary twin terms can be borrowed.

More remotely, cognate terms from different languages can be borrowed, such as ''sauce'' (Old French) and ''salsa'' (Spanish), both ultimately from Latin, or ''tea'' (Dutch ''{{lang|nl|thee}}'') and ''chai'' (Hindi), both ultimately from Chinese. This last pair reflects the history of how tea has entered English via different trade routes.

===English=== Many thousands of English examples can be found, grouped according to their earliest deducible Indo-European ancestor.<ref>Calvert Watkins, ''The American Heritage Dictionary of Indo-European Roots''.</ref> In some cases over a hundred English words can be traced to a single root.

''skin'' is unrelated.

There are many more doublets from Greek, where one form is a vernacular borrowing and the other a learned borrowing, such as ''scandal'' and ''slander'', both from σκάνδαλον.

====Norman vs. standard or Modern French==== Many words of French origin were borrowed twice or more. There were at least three periods of borrowing: one that occurred shortly after the Norman Conquest and came from Norman French, one in the thirteenth and fourteenth centuries from standard (Parisian) French at the time when English nobles were switching from French to English, and a third one during the sixteenth to nineteenth century, when France was at the height of its power and international influence. Examples of doublets from the first and second periods are ''catch'' vs. ''chase'', ''cattle'' vs. ''chattel'', and ''warden'' vs. ''guardian''. More recent borrowings are often distinguished by maintaining the French spelling and pronunciation, e.g. ''chef'' (vs. ''chief''), ''pâté'' (vs. ''paste''), ''fête'' (vs. ''feast''). There are multiple doublets caused by the ''w'' → ''g'' and ''ca'' → ''cha'' sound changes,<ref>{{Cite web |title=The Oxford Guide to Etymology by Philip Durkin |url=https://academic.oup.com/book/5614}}</ref> which happened in standard French but not Norman French. Several of these examples also reflect changes that occurred after Old French which caused the possible environments of {{ipa|[s]}} to be greatly reduced. {| class="wikitable sortable" !colspan=2| English words from French |- !from Norman French !from standard Old or Modern French |- |car||chariot |- |castle||chateau |- |catch||chase |- |cattle||chattel |- |convey||convoy |- |paste||pâté |- |feast||fête |- |hostel||hotel |- |pocket||pouch |- |reward||regard |- |wallop||gallop (also ''galop'', a type of dance) |- |warden||guardian |- |wardrobe||garderobe |- |warranty||guarantee |- |wile, wily||guile |}

===Chinese=== {{Main|Chinese character classification#Derivative cognates|Literary and colloquial readings of Chinese characters}} Derivative cognates are a classification of Chinese characters which have similar meanings and often the same etymological root, but which have diverged in pronunciation and meaning. An example is the doublet {{lang|zh|考}} and {{lang|zh|老}}. At one time they were pronounced similarly and meant "old (person)." {{lang|zh|老}} ({{IPA|/lɑʊ̯˨˩˦/}} in Standard Mandarin) has retained this meaning, but {{lang|zh|考}} {{IPA|/kʰɑʊ̯˨˩˦/}} now mainly means "examine".

Differing literary and colloquial readings of certain Chinese characters are common doublets in many Chinese varieties, and the reading distinctions for certain phonetic features often typify a dialect group. For a given Chinese variety, colloquial readings typically reflect native vernacular phonology. Literary readings are used in some formal settings (recitation, some loanwords and names) and originate from other, typically more prestigious varieties. Sometimes literary and colloquial readings of the same character have different meanings. For example, in Cantonese, the character {{lang|zh|平}} can have the colloquial pronunciation {{IPA|/pʰɛŋ˨˩/}} ("inexpensive"), and the literary pronunciation {{IPA|/pʰɪŋ˨˩/}} ("flat").

===Irish===

The words {{wikt-lang|ga|píosa}} and {{wikt-lang|ga|cuid}} (both meaning "part" or "portion") form an Irish doublet, both from the Proto-Celtic root {{lang|cel-x-proto|kʷesdis}}. This root became in Gaulish {{lang|xtg|pettyā{{lrm}}}}, then was borrowed into Late Latin as {{lang|la|pettia}}, Anglo-Norman ''piece'', then Middle English {{Lang|enm|pece}}, before being borrowed into Middle Irish as {{lang|mga|pissa}}, which became modern {{lang|ga|píosa}}. In Old Irish, {{lang|cel-x-proto|*kʷesdis}} became {{lang|sga|cuit}}, which in modern Irish is {{lang|ga|cuid}}.<ref>{{cite web|url=https://epdf.tips/the-celtic-languages-second-edition-routledge-language-family-series.html|title=The Celtic Languages, Second Edition (Routledge Language Family Series) - PDF Free Download|website=epdf.tips|date=24 July 2009 }}</ref><ref>{{cite web|url=https://www.omniglot.com/blog/?p=13171|title=A Piece of Theatre|last=Simon|date=18 November 2016|website=Omniglot blog}}</ref><ref>{{cite book|url=https://books.google.com/books?id=0Px5DwAAQBAJ&q=kwesdis&pg=PA140|title=Italo-Celtic Origins and Prehistoric Development of the Irish Language|first=Frederik|last=Kortlandt|date=1 January 2007|publisher=BRILL|isbn=978-94-012-0417-0|via=Google Books}}</ref>

===Italian=== * ''macina'' (mill), ''macchina'' (machine): come from Latin ''machina'' * ''soldo'', ''solido'' and ''sodo'' come from Latin ''solidus'' * ''sego'' (animal fat in slaughtered animals) and the medical term ''sebo'' (substance produced by skin) come from Latin ''sebum'' * ''duca'' (duke), doge (chief of Italian state), duce (borrowing from Latin) come from Latin ducem. * ''colpo'' and ''golfo'' come from Greek ''kolpos'' through Latin. * ''ciao'', ''schiavo'' and ''slavo'', ''sloveno'' and slovacco come from Greek ''sklavos'' * ''bestia'' (beast, borrowed from Latin) and ''biscia'' (grass snake) come from Latin ''bestia'' * ''clan'' (through Irish and English) and ''pianta'' (plant). The words ultimately come from Latin ''planta''. * ''esame'', Latin borrowing meaning exam, and ''sciame'', native stock word meaning swarm, both come from Latin ''examen'' * ''prezzo'' (price) and ''pregio'' (quality) come from ''praetium'' * ''causa'' (cause) and ''cosa'' (thing) both come from Latin ''causa''. Italian ''causa'' is a learnt borrowing from Latin, while the Italian word ''cosa'' is inherited from vulgar Latin. * ''sport'' and ''deportare''. Sport is an English borrowing for 'physical activity' while ''deportare'' has the same English meaning of "to deport", that is evicting someone from a country. Both ''sport'' and ''deportare'' come ultimately from Latin dēportō

===New Indo-Aryan=== In Hindi and other New Indo-Aryan languages, members of native doublets are identified as either ''{{lang|sa-Latn|tadbhava}}'' ('became that'), which is ultimately derived from Sanskrit but underwent changes through time, or ''{{lang|sa-Latn|tatsama}}'' ('same as that'), which is borrowed directly from literary Sanskrit. For example, Hindi {{lang|sa-Latn|bāgh|nocat=yes}} 'tiger' is derived by historical stages ({{lang|sa-Latn|tadbhava}}) from Sanskrit {{lang|sa-Latn|vyāghra|nocat=yes}} 'tiger'. Meanwhile, Hindi has also directly borrowed ({{lang|sa-Latn|tatsama}}) the Sanskrit word ''{{lang|sa-Latn|vyāghra}}'', meaning 'tiger' in a more literary register.

Several doublets in Hindustani, which has two standard forms of Hindi and Urdu, come from common Proto-Indo-Iranian roots, with one descending via Sanskrit and another via Persian. These may have stayed synonyms or diverged into different meanings. One example where both patterns can be seen is from the Sanskrit vār (water) and Persian bârân (rain), both from Proto-Indo-Iranian wáHr̥. The Hindustani words for rain include varṣā and barsāt from Sanskrit as well as bāriś from Persian. Meanwhile, the word varṣ from the same root has come to mean year, though often the Persian word sāl is used instead. This word is also a doublet, in this case of the Sanskrit word śarad, which has come to mean the season fall in Hindi.

===Polish=== Triplets: * ''{{lang|pl|upiór}}'', ''{{lang|pl|wąpierz}}'', ''{{lang|pl|wampir}}'' 'vampire' (see the etymology of ''{{lang|pl|wampir|nocat=y}}'') * ''{{lang|pl|szczać}}'' 'piss' (vulgar), ''{{lang|pl|sikać}}'' 'spout' (informal), ''{{lang|pl|siusiać}}'' 'pee' (childish, euphemism; the latter is possibly an irregular diminutive of the former) * ''{{lang|pl|magister}}'', ''{{lang|pl|majster}}'', ''{{lang|pl|mistrz}}'': from German ''{{lang|de|Meister}}'', Dutch ''{{lang|nl|meester}}'', and Latin ''{{lang|la|magister}}''; cognate to Italian ''{{lang|it|maestro}}'', English ''master, mister''

===Spanish=== As with many languages in Europe, a great deal of borrowing from written Latin – ''{{lang|es|latinismos}}'' (Latinisms), or ''cultismos'' (learned words)<ref name=Esp/> – occurred during the Renaissance and the early modern era. Because Spanish is itself a Romance language already with many native words of Latin ancestry (transmitted orally, so with natural sound changes),<ref name=Esp>{{cite book |last=Dworkin |first=Steven N. |title=A History of the Spanish Lexicon |url=https://books.google.com/books?id=V4f8ZpJAhgIC&pg=PA158 |year=2012 |publisher=Oxford University Press |isbn=978-0-19-954114-0 |page=158 }}</ref> the later written borrowing created a number of doublets. Adding to this was Spain's conquest by the Moors in the Middle Ages, leading to another vector for creating doublets (Latin to Arabic to Spanish).

Welsh contains many doublets of native origin, where a single Indo-European root has developed along different paths in the language.

In addition to native doublets, Welsh has borrowed extensively over the centuries, particularly from Latin and English. This has led to many more doublets in the language, including many from Latin that entered Welsh via English borrowings. Examples include:<ref name=":0" />
