embrace: [14] To embrace someone is literally to ‘put your arms round’ them. It comes via Old French from Vulgar Latin *imbracchiāre, a compound verb formed from the prefix in- ‘in’ and Latin bracchium ‘arm’ (ultimate source of English brace, bracelet, and bra, and of French bras ‘arm’). The transferred sense ‘include’ developed in the 17th century (a course also taken by modern French embrasser, whose original ‘clasp in the arms’ has moved on to ‘kiss’ in response to the progression of baiser from ‘kiss’ to ‘have sex with’). => bra, brace, bracelet
mid-14c., "clasp in the arms," from Old French embracier (12c., Modern French embrasser) "clasp in the arms, enclose; covet, handle, cope with," from assimilated form of en- "in" (see en- (1)) + brace, braz "the arms," from Latin bracchium (neuter plural brachia); see brace (n.). Related: Embraced; embracing; embraceable. Replaced Old English clyppan (see clip (v.2)), also fæðm (see fathom (v.)). Sexual sense is from 1590s.
