The kanji 附 is a phono-semantic compound (形声文字). It is composed of the semantic component "阝" (on the left side) which represents "mound" or "slope," and the phonetic component "付" (on the right side) which provides the sound and hints at the meaning. Originally, the left component "阝" was used as a component of the character, later simplified to “阝”. The right component "付" initially meant "to entrust" or "to hand over" but has become associated with the idea of connecting or adding. Together, the components suggest the idea of something being added or adhered to a slope or structure. The phonetic part "付" also hints at the sound and the concept of something being put "near" or "close" to another thing.
