The word 付给 is formed by combining two individual characters, each contributing its core meaning to create a new, compounded concept. The first character, 付 (fù), carries the fundamental idea of "to hand over" or "to pay". The second character, 给 (gěi), introduces the complementary meaning of "to give" or "to provide for". When placed together, they merge into a single verb that emphasizes the complete action of transferring something (like payment or an item) to someone else, with 付 initiating the act of delivery and 给 completing it by specifying the direction or recipient, thus forming a cohesive idea of "to pay to" or "to give over".
