The kanji 附 primarily conveys the idea of attaching, adding, appending, or adhering something to something else. It implies a sense of bringing something into close contact or association. The core meaning revolves around the act of adding something to an existing thing, or the state of something being attached.

The kanji 附 is a phono-semantic compound (形声文字 - keisei moji). It combines the phonetic component 付 (fu - sound) with the semantic component 阝 (a simplified form of 阜, meaning "mound" or "hill"). 付 itself means to "attach" or "add." Therefore, the character originally meant to "attach to a mound" or "add to a high place." Over time, the meaning broadened to encompass attaching or adding things in general.
