Assentive refers to someone who is willing to agree, comply or concur with the opinions or actions of others. There are different words that can be used interchangeably with this adjective. For instance, compliant, acquiescent, cooperative, accommodating, agreeable, or amenable denote people who are willing to go along with the prevailing situation. Other synonyms include submissive, deferential, obsequious or servile, which may carry negative connotations because the person assumes a passive role or obeys orders unquestioningly.
