A device, such as combinations of letters, pictures, or words, to stimulate recall of the facts they represent.

Not Just for High Tech
Mnemonics have been used as verbal tricks to help people remember just about anything. For example "30 days hath September, April, June and November, etc." is a mnemonic rhyme. "Roy G. Biv" spells out the colors of a rainbow: red, orange, yellow, green, blue, indigo and violet.
