The antonyms for the word "disagree" are "agree," "consent," "concur," and "harmonize."
When two or more individuals have different points of view or opinions, they might disagree on a particular subject. However, in a situation where everyone comes to a common ground, they would agree or concur. For instance, in a meeting or discussion, participants would engage in dialogue, share their opinions and reach a consensus on a topic, thus agreeing on a solution. On the other hand, if people do not agree or commute, there could be conflict or misunderstandings, but by focusing on finding a common perspective, they will eventually harmonize.
