The kanji 併 is a phono-semantic compound (形声文字, keisei moji). The left side is a radical related to people (人, nin, hito) or the radical of "person" and suggests association. The right side is 並 (hei, nabi(ku)), which means "to line up" or "to be in parallel," acting as the phonetic component, suggesting the sound and also contributing to the meaning of "together" or "side by side". This combination created the meaning of "to combine" or "to be together".
