Pronunciation

Etymology

It is Middle English committen, borrowed from Latin committere (“to unite, connect, bring together; to entrust; to perpetrate”),[2][3][4][5] in Medieval Latin also “to put into custody”,[6] from com- “with, together” (see com-) and mittere “to release, let go; to send”,[2][3] as in mission.[2][3][4]

Earliest recorded meaning

To give in charge, entrust: about 1386 in the OED, about 1390 in Chaucer in Barnhart.[7][3]

Semantic evolution

Etymonline notes that the development of the modern senses in English is not entirely clear.[2] To consign someone to custody, in prison or later in a mental institution, is from the early 15th century,[2] 1467 in the OED with a prison named.[7] The sense “to perpetrate a crime or do something wrong” was old in Latin and appears in English in the mid-15th century, 1449 in Barnhart.[2][3] To trust oneself completely to something is from the 1530s,[2][7] and to commit to writing from 1568.[7] To involve oneself, or bind oneself by an irrevocable act, is from 1770,[2] and Hoad dates the sense “engage, involve” to the 17th century.[4] The intransitive use, in place of commit oneself, is by 1982, probably influenced by the existentialist sense of commitment (1948).[2] Commitment meant the committing of a sin or crime in 1611 and a pledge from 1793, in Thomas Jefferson.[3]
