Origin

This character combines the "attach" radical on the left, which relates to connection or fastening, with the component 付 on the right that serves as a sound hint for how to pronounce the character. The left component carries the core meaning of something being affixed or attached to another thing, while the right component doesn't add semantic meaning but instead guides readers toward the character's pronunciation. Together they create a character specifically for expressing the idea of attaching or appending something to an object.
