"a slight push with the elbow," 1787, from nudge (v.). Figurative sense of "a signal or hint intended to call attention, remind, etc." is by 1831.
1962, vulgar or working class pronunciation of hoy a call or shout to attract attention (compare ahoy).
It forms all or part of: call; clatter; Gallic; gallinaceous; gallium; glasnost; Glagolitic.
It is the hypothetical source of/evidence for its existence is provided by: Sanskrit garhati "bewail, criticize;" Latin gallus "cock;" Old English ceallian "to shout, utter in a loud voice," Old Norse kalla "to cry loudly," Dutch kallen "to talk, chatter;" German Klage "complaint, grievance, lament, accusation;" Old English clacu "affront;" Old Church Slavonic glasu "voice," glagolu "word;" Welsh galw "call."
1650s, "to select (someone) for a group or club by a vote of members," from Latin cooptare "to elect, to choose as a colleague or member of one's tribe," from assimilated form of com- "together" (see com-) + optare "choose" (see option (n.)). For some reason this defied the usual pattern of Latin-to-English adaptation, which should have yielded co-optate (which is attested from 1620s but now is rare or obsolete). Sense of "take over" is first recorded c. 1953. Related: Co-opted; co-opting.
early 15c., "spiritual calling," from Old French vocacion "call, consecration; calling, profession" (13c.) or directly from Latin vocationem (nominative vocatio), literally "a calling, a being called" from vocatus "called," past participle of vocare "to call," which is related to vox (genitive vocis) "voice" (from PIE root *wekw- "to speak"). Sense of "one's occupation or profession" is first attested 1550s.
"named, called" (archaic), from levelled past participle of Middle English highte, from Old English hatte "I am called" (passive of hatan "to call, name, command") merged with heht "called," active past tense of the same verb. Hatte was the only survival in Old English of the old Germanic synthetic passive tense. Proto-Germanic *haitanan "to call, summon," also is the source of Old Norse heita, Dutch heten, German heißen, Gothic haitan "to call, be called, command," and is perhaps from an extended form of PIE root *keie- "to set in motion," but Boutkan finds it to be of uncertain origin.
c. 1300, "to call, call out; to ask or demand by virtue of right or authority," from accented stem of Old French clamer "to call, name, describe; claim; complain; declare," from Latin clamare "to cry out, shout, proclaim," from PIE root *kele- (2) "to shout." Related: Claimed; claiming.
Meaning "to maintain as true, assert a belief or opinion" is from 1864 ("A common use, regarded by many as inelegant" - Century Dictionary, 1895); claim properly should not stray too far from its true meaning of "to demand recognition of a right." Specific sense "to make a claim" (on an insurance company) is from 1897.
early 14c., reclaimen, "call back a hawk to the glove," from Old French reclamer "to call upon, invoke; claim; seduce; to call back a hawk" (12c., Modern French réclamer) and directly from Latin reclamare "cry out against, contradict, protest, appeal," from re- "opposite, against" (see re-) + clamare "cry out" (from PIE root *kele- (2) "to shout").
"Call out; call back a hawk," hence "make tame" (mid-15c.), "subdue, reduce to obedience, make amenable to control" (late 14c.). Many Middle English senses lack an apparent notion of return or reciprocation (not unusual with Middle English re- words). Meaning "revoke" (a grant, gift, etc.) is from late 15c. That of "recall (someone) from an erring course to a proper state" is from mid-15c.
The sense of "get back by effort" might reflect influence of claim. The specific meaning "bring waste land into useful condition fit for cultivation" is attested by 1764, probably on notion of "reduce to obedience" (perhaps from the image of taming wild animals) rather than a suggestion of a return to a previous condition.
