However, there are a multitude of synonyms that can be used to express this same idea. For example, some other ways to say that two people have a good relationship with each other could be: "hit it off," "bonded," "jived," "connected," "gelled," "clicked," "meshed," "vibed," or "related well." Whether it's in a professional or personal setting, being able to communicate effectively about how individuals work together is important for fostering positive relationships and promoting success.
