The kanji 限 is a phono-semantic compound (形声文字). It is composed of the semantic component 阜（こざとへん） - meaning "hill" or "mound," and the phonetic component 艮 (gon), which originally meant "to restrain" or "to stop." The original meaning was related to a boundary marked by a hill or something that sets a limit or boundary. Over time, the meaning shifted towards the general idea of limit, restriction, or boundary.
