1530s, "fit one thing to another," from Latin accomodatus "suitable, fit, appropriate to," past participle of accomodare "make fit, make fit for, adapt, fit one thing to another," from ad "to" (see ad-) + commodare "make fit," from commodus ""proper, fit, appropriate, convenient, satisfactory," from com-, here as an intensive prefix (see com-), + modus "measure, manner" (from PIE root *med- "take appropriate measures"). From late 16c. as "make suitable," also "furnish (someone) with what is wanted," especially "furnish with suitable room and comfort" (1712). Related: Accommodated; accommodating.
1620s, "an embrace about the neck then the tapping of a sword on the shoulders to confer knighthood," from French accolade "an embrace, a kiss" (16c.), from Provençal acolada or Italian accollata, ultimately from noun use of a fem. past participle of Vulgar Latin *accollare "to embrace around the neck," from Latin ad "to" (see ad-) + collum "neck" (compare collar (n.)), from PIE root *kwel- (1) "revolve, move round." Also see -ade. The extended meaning "praise, award" is by 1851. The earlier form of the word in English was accoll (mid-14c.), from Old French acolee "an embrace, kiss, especially that given to a new-made knight," a noun use of the past participle of the verb acoler. The French noun in the 16c. was altered to accolade, with the foreign suffix, and English followed suit.
"upward slope of ground," 1610s, from Latin acclivitatem (nominative acclivitas) "an ascending direction, rising grade, upward steepness," from acclivis "mounting upwards, ascending," from ad "to, up to" (see ad-) + clivus "hill, a slope" (from PIE *klei-wo-, suffixed form of root *klei- "to lean").
in geology, "leaning against," as one stratum of rock against another, both turned up at an angle, 1837, from Latin acclinis "leaning on or against," related to acclinare "to lean on or against," from assimilated form of ad "to, upon" (see ad-) + clinare "to bend" (from PIE *klein-, suffixed form of root *klei- "to lean").
1792, "habituate (something) to a new climate," from French acclimater, verb formed from à "to" (see ad-) + climat (see climate). Intransitive sense "adapt to a new climate" is from 1861. Related: Acclimated; acclimating. The extended form acclimatize is now more common in the older sense of this word (generally in reference to plants or animals), leaving to this word the intransitive sense, which more often refers to humans.
1540s, "act of shouting or applauding in approval," from Latin acclamationem (nominative acclamatio) "a calling, exclamation, shout of approval," noun of action from past-participle stem of acclamare "to call to, cry out at, shout approval or disapproval of," from assimilated form of ad "to, toward" (see ad-) + clamare "cry out" (from PIE root *kele- (2) "to shout"). As a method of spontaneous approval of resolutions, etc., by unanimous voice vote, by 1801, probably from the French Revolution.
early 14c., "to lay claim to," from Latin acclamare "to cry out at" (in Medieval Latin "to claim"), from ad "to, toward" (see ad-) + clamare "cry out" (from PIE root *kele- (2) "to shout"). The meaning "to applaud" is recorded by 1630s. The spelling has been conformed to claim. Related: Acclaimed; acclaiming; acclamatory.
raptorial bird, 1708, from Latin accipiter, a generic name for birds of prey, especially the common hawk. According to de Vaan, "generally assumed" to be from a Proto-Italic *aku-petri- "having pointed (that is, 'swift') wings" (see acro- + ptero-) and compares Greek okypteros "with swift wings," Sanskrit asu-patvan- "flying swiftly," "all of which are used as epithets to birds of prey." Under this theory the initial acc- is by influence of the verb accipere "to take" (whence also Latin acceptor "falcon;" see accept). Or the sense could be literal, "with pointed wings." The proper plural would be accipitres. Related: Accipitral; accipitrine (1809).
