commit Look up commit at Dictionary.com
late 14c., from L. committere "to bring together," from com- "together" + mittere "to put, send" (see mission). Evolution into modern range of meanings is not entirely clear. Sense of "perpetrating" was ancient in Latin. The intransitive use (in place of commit oneself) first recorded 1982, probably influenced by existentialism use (1948) of commitment to translate Sartre's engagement "to emotionally and morally engage."
