“Consentient” appears to bridge two familiar words — “consent” and “sentient” — yet its meaning is different from either. Though “consentient” is built on the same Latin root as “consent,” the latter word is now largely used as a synonym for “permission” or “acceptance.” This implies one party is granting permission to another, while the meaning of “consentient” implies both or multiple parties are coming to a mutual agreement. There might be debate and compromise involved in coming to a consentient arrangement. “Sentient” is an adjective that implies the ability to perceive or feel things. While understanding the feelings of someone else during the process of coming to an agreement is important, the definitions of the words are not related.
