Sideman → It is formed from "side" (from Old English "side", meaning the lateral part or position) and "man" (from Old English "mann", meaning a human being). The word "sideman" refers to a person who is positioned at the side, often in a supportive role.
Think of someone who stands at the 'side' — that's what a sideman is, a person who supports or assists from the side.
