The kanji 込 is a phono-semantic compound (形声文字). It is composed of the radical 辶 (しんにょう - shinnyou) which means "to walk" or "to move" on the left, and 公 (こう - kou) on the right. 公 originally meant "public" or "official". The combination suggests the action of moving something into a specific space or the idea of putting something into a public sphere. The 辶 radical modifies the meaning of 公, focusing on the action of movement and insertion.
