Usage notesUse 'cousin' when referring to family members who share grandparents but not parents. It's appropriate in both spoken and written contexts. In more formal discussions about family, you might specify 'first cousin' or 'second cousin'.Use 'relative' to refer to family members in a general sense. In formal contexts, it's suitable to discuss familial connections; in informal settings, it's often used casually. Avoid using it for non-familial connections.
