Past tense of acquiesce; agreed or accepted something without protest, even though you might not entirely approve.
From Latin acquiescere (ad + quiescere, 'to rest' or 'become quiet'). The root quiescere means 'to be quiet or inactive,' so acquiesce literally means 'to become quiet at' something, implying acceptance without objection.
Acquiesced has a special meaning—it's not enthusiastic agreement like 'yes!' but rather reluctant acceptance, like when you disagree but go along with someone to keep the peace. It's diplomatic disagreement!
