pool <small body of water, from Old English *pōl*>
Etymology

The word "pool" traces back to Old English pōl, meaning a small body of water, likely derived from Proto-Germanic *pōlaz. It retains its core meaning of a contained liquid but expanded metaphorically to describe collective resources (e.g., "car pool") in the 19th century. The verb form emerged from this shared-resource concept.
