c. 1600, "action of adapting (something to something else)," from French adaptation, from Late Latin adaptationem (nominative adaptatio), noun of action from past-participle stem of adaptare "to adjust," from ad "to" (see ad-) + aptare "to join," from aptus "fitted" (see apt).
Meaning "condition of being adapted, state of being fitted to circumstances or relations" is from 1670s. Sense of "modification of a thing to suit new conditions" is from 1790. Biological sense "variations in a living thing to suit changed conditions" first recorded 1859 in Darwin's writings.
"act of making popular, adaptation to popular needs or capacities," 1797, noun of action from popularize.
seed from which cocoa and chocolate are made, 1550s, from Spanish cacao "the cocoa bean," an adaptation of Nahuatl (Aztecan) cacaua, root form of cacahuatl "bean of the cocoa-tree."
legendary Greek sculptor/goldsmith who created a beautiful statue of a woman he made and wished to life, from Greek Pygmaliōn. The story is centered on Cyprus and his name might be a Greek folk-etymology adaptation of a foreign word, perhaps from Phoenician. Notable in 20c. for the Pygmalion word, a British euphemistic substitute for bloody, from the notorious use of that word in Bernard Shaw's "Pygmalion" (1913: "Walk? Not bloody likely!"), the basis of the 1964 movie "My Fair Lady."
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.
