Origin: 1570–80; < Medieval Latin capitulātus (past participle of capitulāre to draw up in sections), equivalent to capitul(um) section (literally, small head; see capitulum) + -ātus-ate1
1580, "to draw up in chapters" (i.e., under "heads"), from M.L. capitulatus, pp. of capitulare "to draw up in heads or chapters, arrange conditions" (see capitulation). Often of terms of surrender, hence meaning "to yield on stipulated terms" (1689). Capitulated is from 1586; capitulating from 1654.
