Probably you know this one already. ROY G BIV. The order of the colors of a rainbow.
Red, Orange, Yellow, Green, Blue, Indigo, Violet.

Setting a table four lettered items like fork, go on the left (left has four letters) and five letter items like knife and spoon, on the right.

On a boat “port” is left. Both words have 4 letters.
