Portside → It is formed from "port" (from Old French *port*, meaning harbor or gate) and "side" (from Old English *side*, meaning the lateral part of something). The term "portside" refers to the left side of a ship when facing forward, which is associated with the harbor side.
Think of the word 'port' meaning harbor and 'side' referring to a lateral part — this helps you remember that 'portside' is the left side of a ship, typically facing the harbor.
