The kanji 岡 is a 形声文字 (keisei moji), a phono-semantic compound. It combines the phonetic component [工] (kō), which originally represented a tool or building, with the semantic component [山] (yama), meaning "mountain." This combination suggests a small, constructed-like or tool-like part of a mountain or a small hill. The character likely evolved to visually represent a portion of the "mountain" or "hill."
