The word "顺带" is formed by combining the character "顺", which means "along with" or "in passing", with the character "带", which means "to carry" or "to bring". Together, they create a compound word where "顺" conveys the sense of doing something concurrently or conveniently, and "带" adds the notion of including or performing an additional action, resulting in the meaning of doing something incidentally or as a secondary task.
