contingent

Etymology

It is borrowed from Middle French contingent, recorded from the 14th century in Oresme,^[2][3] or else borrowed from Latin contingēns (“touching; befalling, happening”), the present participle of contingō (“to touch on all sides; to befall, happen”),^[2][4][3][5] formed from com- (“together”) and tangō (“to touch”).^[2][3][6][7] In Medieval Latin the participle also meant "possible, contingent".^[4] The OED notes that the letter n of the Latin verb belongs only to its present stem.^[2] It is related to contact, contiguous, contagion and tangent.^[5][8][6]

Earliest recorded meaning

Liable to happen or not; of uncertain occurrence: about 1400, in the Testament of Love,^[2] late 14th century in Etymonline,^[4] and about 1385 in Barnhart.^[5] The Shorter Oxford dates it to late Middle English.^[9]

Semantic evolution

The word developed along two lines from the senses of the Latin verb.^[2] From "to touch" came a geometrical sense, "touching, tangential", recorded from about 1560 and now rare.^[2][9] From "to happen" came most of the others: "happening by chance, accidental" from 1604,^[2][4] in logic "true only under existing conditions, not necessarily true" from 1588,^[2][9] "dependent on some prior condition" from 1613,^[10] and in law "provisionally liable to take effect, conditional" from 1710.^[10] In theology and philosophy it meant "not determined by necessity, free" from 1660 to 1796.^[2][9] Johnson (1755) defined the adjective as "falling out by chance; accidental".^[11] The noun first meant a thing happening by chance (1548),^[2][5][3] then a possible future event (1655).^[10] The Oxford Dictionary of English traces the modern noun through the sense "a person's share resulting from a division, a quota",^[7] which Johnson defined as the proportion that falls to anyone in a division;^[10] from the early 18th century it was used of the share of troops that each power in an alliance had to supply;^[4][12][7] since 1891 it has also meant any group forming part of a larger gathering.^[10] Weekley instead connects the military sense with that of "liable to occur", as in contingency.^[12]
