'''Etymology''' ({{IPAc-en|ˌ|ɛ|t|ɪ|ˈ|m|ɒ|l|ə|dʒ|i}} {{respell|ET|ih|MOL|ə|jee}})<ref name="OED">{{OED|Etymology |quote=the scientific study of words and the way their meanings have changed throughout time}}</ref> is the study of the origin and evolution of words—including their constituent units of [[phoneme|sound]] and [[morpheme|meaning]]—across time.<ref>{{multiref |{{OEtymD|etymology}} |{{cite Dictionary.com|etymology}} |{{cite Merriam-Webster|etymology}} |{{cite Cambridge Dictionaries|etymology}}}}</ref> In the 21st century a subfield within [[linguistics]], etymology has become a more rigorously scientific study.<ref name="OED" /> Most directly tied to [[historical linguistics]], [[philology]], and [[semiotics]], it additionally draws upon comparative [[semantics]], [[morphology (linguistics)|morphology]], [[pragmatics]], and [[phonetics]] in order to attempt a comprehensive and chronological catalogue of all meanings and changes that a word (and its related parts) carries throughout its history. The origin of any particular word is also known as its ''etymology''.

For languages with a long [[written history]], etymologists make use of texts, particularly texts about the language itself, to gather knowledge about how words were used during earlier periods, how they developed in meaning and [[phonological change|form]], or when and how they entered the language. Etymologists also apply the methods of [[comparative linguistics]] to reconstruct information about forms that are too old for any direct information to be available. By analyzing related languages with a technique known as the [[comparative method]], linguists can make inferences about their shared parent language and its vocabulary. In this way, [[word roots]] in many European languages, for example, can be traced back to the origin of the [[Indo-European language family]].

Even though etymological research originated from the philological tradition, much current etymological research is done on language families where little or no early documentation is available, such as [[Uralic]] and [[Austronesian languages|Austronesian]].

== Etymology ==

The word ''etymology'' is derived from the Ancient Greek word {{wikt-lang|grc|ἐτυμολογία}} ({{transliteration|grc|etymologíā}}), itself from {{wikt-lang|grc|ἔτυμον}} ({{transliteration|grc|étymon}}), meaning {{gloss|true sense or sense of a truth}}, and the suffix {{transliteration|grc|-logia}}, denoting {{gloss|the study or logic of}}.<ref>{{OEtymD|etymology}}</ref><ref>{{LSJ|e)tumologi/a|ἐτυμολογία}}, {{LSJ|e)/tumos|ἔτυμον|ref}}.</ref>

The ''etymon'' refers to the predicate (i.e. stem<ref>According to [[Ghil'ad Zuckermann]], the ultimate etymon of the English word ''machine'' is the Proto-Indo-European stem {{lang|ine-x-proto|māgh}} {{gloss|be able to}}, see {{harvnb|Zuckermann|2003|p=174}}.</ref> or root<ref>According to [[Ghil'ad Zuckermann]], the co-etymon of the modern Israeli Hebrew word {{tlit|he|glida}} {{gloss|ice cream}} is the Hebrew root {{tlit|he|gld}} {{gloss|clot}}, see p. 132, {{cite book |last=Zuckermann |first=Ghil'ad |year=2003 |title=Language Contact and Lexical Enrichment in Israeli Hebrew |publisher=Palgrave Macmillan |isbn=978-1-4039-1723-2}}</ref>) from which a later word or morpheme derives. For example, the Latin word {{lang|la|candidus}}, which means {{gloss|white}}, is the etymon of English ''candid''. Relationships are often less transparent, however. English [[place names]] such as ''[[Winchester]]'', ''[[Gloucester]]'', ''[[Tadcaster]]'' share different forms of a [[suffix]] that originated as the Latin {{lang|la|castrum}} {{gloss|fort}}.

''Reflex'' is the name given to a descendant word in a daughter language, descended from an earlier language. For example, Modern English heat is the reflex of the Old English {{lang|ang|hǣtu}}. Rarely, this word is used in reverse, and the reflex is actually the root word rather than the descendant word. However, this usage is usually filled by the term ''etymon'' instead. A reflex will sometimes be described simply as a ''descendant'', ''derivative'' or ''derived'' from an etymon (but see below).{{citation needed|date=July 2024}}

''[[Cognates]]'' or ''lexical cognates'' are sets of words that have been inherited in direct descent from an etymological ancestor in a common parent language.<ref>{{cite dictionary |editor-last=Crystal |editor-first=David |editor-link=David Crystal |year=2011 |dictionary=A Dictionary of Linguistics and Phonetics |edition=6th |url=https://books.google.com/books?id=3ZPQVuSgDAkC&pg=PT104 |title=Cognate |publisher=Blackwell |pages=104, 418 |isbn=978-1-4443-5675-5}}</ref>  ''Doublets'' or ''etymological twins'' or ''twinlings'' (or possibly triplets, and so forth) are specifically cognates within the same language. Although they have the same etymological root, they tend to have different phonological forms, and to have entered the language through different routes.

A ''[[root (linguistics)|root]]'' is the source of related words within a single language (no language barrier is crossed).
Similar to the distinction between ''etymon'' and ''root'', a nuanced distinction can sometimes be made between a ''descendant'' and a ''derivative''.

A ''[[derivative (linguistics)|derivative]]'' is one of the words which have their source in a root word, and were at some time created from the root word using morphological constructs such as suffixes, prefixes, and slight changes to the vowels or to the consonants of the root word. For example: ''unhappy'', ''happily'', and ''unhappily'' are all derivatives of the root word ''happy''. The terms ''root'' and ''derivative'' are used in the analysis of [[Morphology (linguistics)|morphological]] derivation within a language in studies that are not concerned with historical linguistics and that do not cross the language barrier.

== Methods ==
[[File:Etymological relations tree.svg|thumb|Graphical representation of the relationships between etymologically-related words. 'Etymon' is used in linguistic jargon, while 'root' is the more common colloquial term.]]
Etymologists apply a number of methods to study the origins of words, some of which are:
* [[Philological]] research. Changes in the form and meaning of the word can be traced with the aid of older texts, if such are available.
* Making use of [[dialectological]] data. The form or meaning of the word might show variations between [[dialect]]s, which may yield clues about its earlier history.
* The [[comparative method]]. By a systematic comparison of related languages, etymologists may often be able to detect which words derive from their common ancestor language and which were instead later borrowed from another language.
* The study of [[semantic change]]. Etymologists must often make hypotheses about changes in the meaning of particular words. Such hypotheses are tested against the general knowledge of semantic shifts. For example, the assumption of a particular change of meaning may be substantiated by showing that the same type of change has occurred in other languages as well.

== Types of word origins ==
Etymological theory recognizes that words originate through a limited number of basic mechanisms, the most important of which are [[language change]], borrowing (i.e., the adoption of [[loanwords]] from other languages); [[word formation]] such as [[Derivation (linguistics)|derivation]] and [[Compound (linguistics)|compounding]]; and [[onomatopoeia]] and [[sound symbolism]] (i.e., the creation of imitative words such as ''click'' or ''grunt'').

While the origin of newly emerged words is often more or less transparent, it tends to become obscured through time due to sound change or semantic change. Due to [[sound change]], it is not readily obvious that the English word ''set'' is related to the word ''sit'' (the former is originally a [[causative]] formation of the latter). It is even less obvious that ''bless'' is related to ''blood'' (the former was originally a derivative term meaning 'to mark with blood').

Semantic change may also occur. For example, the English word ''bead'' originally meant 'prayer', and acquired its modern meaning through the practice of counting the recitation of prayers by using small objects strung together (beads). One type of semantic change involves the quotidianisation of [[metaphor]].<ref>

Thus the word "trauma", the predecessors of which apparently referenced an "open hole" in the body, has passed through some metaphorical stage or stages and now often refers to some sort of psychological wound.<ref>

== History ==
The search for meaningful origins for familiar or strange words is far older than the modern understanding of linguistic evolution and the relationships of languages, which began no earlier than the 18th century. Etymology has been a form of witty wordplay, in which the supposed origins of words were creatively imagined to satisfy contemporary requirements. For example, the Greek poet [[Pindar]] (born {{circa|522&nbsp;BCE}}) employed inventive etymologies to flatter his patrons. [[Plutarch]] employed etymologies insecurely based on fancied resemblances in sounds. [[Isidore of Seville]]'s ''{{lang|la|[[Etymologiae]]}}'' was an encyclopedic tracing of "first things" that remained uncritically in use in Europe until the sixteenth century. ''{{lang|la|[[Etymologicum Genuinum]]}}'' is a grammatical encyclopedia edited at [[Constantinople]] during the 9th century, one of several similar [[Byzantine]] works. The 13th-century ''[[Golden Legend]]'', as written by [[Jacobus de Voragine]], begins each [[hagiography]] of a saint with a fanciful [[excursus]] in the form of an etymology.<ref>{{Cite book |url=https://books.google.com/books?id=Ek1skuzIZH0C&q=legenda+aurea+etymology+beginning&pg=PA27 |title=Women of the Gilte Legende: A Selection of Middle English Saints Lives |last1=Jacobus |last2=Tracy |first2=Larissa |year=2003 |publisher=DS Brewer |isbn=978-0-85991-771-1}}</ref>

=== Sanskrit ===
{{Main|Nirukta}}
In [[ancient India]], [[Sanskrit]] linguists and grammarians were the first to undertake comprehensive analyses of linguistics and etymology. The study of Sanskrit etymology has provided Western scholars with the basis of [[historical linguistics]] and modern etymology. Four of the most famous Sanskrit linguists are:
* [[Yāska]] ({{circa|6th–5th centuries&nbsp;BCE}})
* [[Pāṇini]] ({{Circa|520–460&nbsp;BCE|lk=no}})
* [[Kātyāyana]] (6th-4th centuries&nbsp;BCE)
* [[Patanjali]] (2nd century&nbsp;BCE)

These were not the earliest Sanskrit grammarians, but rather followed an earlier line of scholars who lived several centuries earlier, who included [[Śākaṭāyana]] (814–760&nbsp;BCE), and of whom very little is known. The earliest of attested etymologies can be found in the [[Vedas]], in the philosophical explanations of the [[Brahmana]]s, [[Aranyaka]]s, and [[Upanishads]].

The analyses of [[Vyākaraṇa|Sanskrit grammar]] done by the previously mentioned linguists involved extensive studies on the etymology (called {{tlit|sa|[[Nirukta]]}} or {{tlit|sa|Vyutpatti}} in Sanskrit) of Sanskrit words, because the ancient Indians considered sound and speech itself to be sacred and, for them, the words of the Vedas contained deep encoding of the mysteries of the soul and God.

=== Greco-Roman ===
One of the earliest philosophical texts of the Classical Greek period to address etymology was the [[Socratic dialogue]] ''[[Cratylus (dialogue)|Cratylus]]'' ({{circa|360&nbsp;BCE|lk=no}}) by [[Plato]]. During much of the dialogue, [[Socrates]] makes guesses as to the origins of many words, including the names of the gods. In his [[ode]]s, Pindar spins complimentary etymologies to flatter his patrons. [[Plutarch]] (''Life of [[Numa Pompilius]]'') spins an etymology for {{lang|la|[[Pontifex maximus|pontifex]]}},  while explicitly dismissing the obvious, and actual "bridge-builder":<!-- Should this begin with a capitalized T or an ellipsis? Question posed May 2015, since there is no reference to answer it. -->
<blockquote>The priests, called Pontifices.... have the name of Pontifices from {{lang|la|potens}}, powerful because they attend the service of the gods, who have power and command overall. Others make the word refer to exceptions of impossible cases; the priests were to perform all the duties possible; if anything lays beyond their power, the exception was not to be cavilled. The most common opinion is the most absurd, which derives this word from pons, and assigns the priests the title of bridge-makers. The sacrifices performed on the bridge were amongst the most sacred and ancient, and the keeping and repairing of the bridge attached, like any other public sacred office, to the priesthood.</blockquote>

=== Medieval ===
{{Main|Medieval etymology}}
[[Isidore of Seville]] compiled a volume of etymologies to illuminate the triumph of religion. Each saint's legend in [[Jacobus de Voragine]]'s ''[[Golden Legend]]'' begins with an etymological discourse on their name:
<blockquote> Lucy is said of light, and light is beauty in beholding, after that S. Ambrose saith: The nature of light is such, she is gracious in beholding, she spreadeth over all without lying down, she passeth in going right without crooking by right long line; and it is without dilation of tarrying, and therefore it is showed the blessed Lucy hath beauty of virginity without any corruption; essence of charity without disordinate love; rightful going and devotion to God, without squaring out of the way; right long line by continual work without negligence of slothful tarrying. In Lucy is said, the way of light.<ref>{{Cite web |url=http://www.fordham.edu/halsall/basis/goldenlegend/GoldenLegend-Volume2.htm#Lucy |title=Medieval Sourcebook: The Golden Legend: Volume 2 (full text) |access-date=2005-05-28 |archive-date=2000-12-09 |archive-url=https://web.archive.org/web/20001209054700/http://www.fordham.edu/halsall/basis/goldenlegend/GoldenLegend-Volume2.htm#Lucy |url-status=dead}}</ref> </blockquote>


=== Islamic Golden Age ===
During the [[Islamic Golden Age]] between the 8th and 14th centuries, several scholars laid the foundations of systematic etymology in Arabic. In the 8th century, [[al-Khalil ibn Ahmad al-Farahidi|al‑Khalīl ibn Aḥmad al‑Farāhīdī]] compiled the first [[Arabic]] dictionary, ''[[Kitab al-'Ayn]]'' ({{langx|ar|كتاب العين}} "The Source"), in which he organized entries by root and phonetic properties rather than alphabetic order, and provided etymological commentaries tracing word meanings to their [[semitic root|triliteral]] origins.<ref name="shamela.ws">{{ cite book|last=al-Farahidi|first=Al-khalil|authorlink=al-Khalil ibn Ahmad al-Farahidi|title=Al-Ayn Lexicon كتاب العين|publisher=مركز التراث للبرمجيات|location=Riyadh|url=https://shamela.ws/book/1682/1915|language=Arabic|page=343/5}}</ref>{{Request quotation|date=August 2025}}<ref>{{cite book|isbn=9780878406630|year=1998|publisher=[[Georgetown University Press]]|location=[[Washington, D.C.]]|title=''Introduction to'' Early Medieval Arabic: Studies on Al-Khalīl Ibn Ahmad|page=3|last1=Ryding|first1=Karin C.}}</ref>

=== Modern era ===
{{Further|Comparative method}}

Etymology in the modern sense emerged in the late 18th-century European academia, in the context of the [[Age of Enlightenment]], although preceded by 17th-century pioneers such as [[Marcus Zuerius van Boxhorn]], [[Gerardus Vossius]], [[Stephen Skinner (lexicographer)|Stephen Skinner]], [[Elisha Coles]], and [[William Wotton]].  The first known systematic attempt to prove the relationship between two languages on the basis of similarity of [[grammar]] and [[lexicon]] was made in 1770 by the Hungarian, [[János Sajnovics]], when he attempted to demonstrate the relationship between [[Sami languages|Sami]] and [[Hungarian language|Hungarian]].<ref name="ssix">Szemerényi 1996:6</ref>

The origin of modern [[historical linguistics]] is often traced to [[William Jones (philologist)|William Jones]], a Welsh philologist living in India, who in 1782 observed the genetic relationship between Greek and Latin. Jones published his ''The Sanscrit Language'' in 1786, laying the foundation for the field of [[Indo-European studies]]. However, as early as 1727, a Jesuit missionary in India, père Gargam, theorized that Sanskrit could be a "mother tongue arrived from another country" for [[Telugu language|Telugu]] and [[Kannada]] because they contained many of the same Sanskrit terms; and in a letter to Abbé Barthélemy of the [[Académie des Inscriptions et Belles-Lettres|Académie des Inscriptions et Belles Lettres]] in 1767, another Jesuit missionary in India, père [[Gaston-Laurent Coeurdoux]], posed the question of the origin of the Sanskrit language and systematically argued his hypothesis of a "commune origine" of Sanskrit, Latin, and Greek, even putting Sanskrit terms and their Latin equivalents in columns.<ref name=":0">{{Cite book |last=Colas |first=George |title=Le Sanctuaire Devoilé.

The study of etymology in [[Germanic philology]] was introduced by [[Rasmus Rask]] in the early 19th century and elevated to a high standard with the ''{{lang|de|[[Deutsches Wörterbuch]]}}'' (''German Dictionary'') compiled by the [[Brothers Grimm]]. The successes of the comparative approach culminated in the [[Neogrammarian]] school of the late 19th century. Still, [[Friedrich Nietzsche]] used etymological strategies (principally and most famously in ''[[On the Genealogy of Morality]]'', but also elsewhere) to argue that moral values have definite historical origins, where the meaning of concepts such as good and evil are shown to have changed over time according to the value-system that appropriates them. This strategy gained popularity in the 20th century, and philosophers, such as [[Jacques Derrida]], have used etymologies to indicate former meanings of words to de-center the "violent hierarchies" of Western philosophy.
