joins
"Joins" is the third-person singular present form of the verb "join." It has a few closely related but distinct meanings, all revolving around the idea of connecting, combining, or becoming part of something.
When someone joins an activity, a conversation, or an effort, they start participating in it alongside others. It is slightly different from joining a group — here the focus is on the action, not the membership.
