consent: [13] The notion underlying ‘giving one’s consent’ is ‘feeling together’ – that is, ‘agreeing’, and hence ‘giving approval or permission’. The word comes from Old French consente, a derivative of the verb consentir. This was a descendant of Latin consentīre ‘agree’, a compound verb formed from the prefix com- ‘together’ and sentīre ‘feel’ (source of English sense, sentence, sentiment, etc). Consensus, originally the past participle of Latin consentīre, was borrowed into English in the 19th century.

early 13c., from Old French consentir (12c.) "agree, comply," from Latin consentire "feel together," from com- "with" (see com-) + sentire "to feel" (see sense (n.)). "Feeling together," hence, "agreeing, giving permission," apparently a sense evolution that took place in French before the word reached English. Related: Consented; consenting.
