The origins of Port and Starboard on ships.
Chosen to be independent of a mariners orientation.
Starboard - most sailors were right handed and the steering oar was placed on the right. Star = steer. Board = side of boat.
Port - as steering oars got bigger, boats tended to dock on the left hand side. This became to be known as “lardboard” which sounded too much like starboard, so it was changed to “Port” (as in the side typically facing the port side.
In French, there is babord and tribord. The mnemonic is ba-tri, or “battery”.
A fun mnemonic I use to remember port is to the left is "lp unix command = line printer = left to port".
