  • /ˈæd͡ʒ.ʌŋkt/[1]

Etymology

It is borrowed from Latin adiūnctus (“joined, connected, associated; adjacent”),[2][3][4][5] the past participle of adiungō (“to join to, link up, add”),[2][6][4][7] formed from ad- (“to”) and iungō (“to join”).[5][8] The noun is partly modelled on the neuter adiūnctum (“a concomitant factor; in logic, an essential attribute”).[2][6] Etymonline notes that the sense of subordination usual in English is not in the Latin.[3] The word is the Latin counterpart of adjoin, which came through French,[4][9][10] and Dictionary.com connects the stem of the Latin verb with the source of yoke.[8]

Earliest recorded meaning

As an adjective, associated, joined or subordinate: 1516, in a Scottish record, the “Registrum Secreti Sigilli Regum Scotorum”.[2][6] Hoad likewise notes that the word is found earlier in Scots.[10] Barnhart's first records are from Shakespeare: the noun in Love's Labour's Lost (1588) and the adjective in King John (1595),[7] and Etymonline dates the noun to the 1580s and the adjective to the 1590s.[3]

Semantic evolution

The noun appeared in the mid-16th century for a person joined to another as an assistant or subordinate (1554),[2][6] and for something joined to another thing but dependent on it (1566).[2] In logic an adjunct was a non-essential quality or circumstance of a thing (1581),[2][6] and in grammar a word or group of words that amplifies or modifies another (1588);[2] in 1914 Jespersen gave it a narrower technical sense, a word of secondary rank in a phrase.[2] Johnson (1755) defined the noun as something united to another without being an essential part of it.[11] In medicine an adjunct has since 1756 been a treatment that supplements another.[2] In American education adjunct has named a junior, temporary or part-time academic post since 1785, chiefly in adjunct professor;[2][6] Barnhart and Etymonline date that title to 1826.[7][3]
