Mnemonics
Greek: mnēmonikós - of, relating to memory
"A device, such as a verse or formula or rhyme, used as an aid in remembering concepts. Named for Mnemosyne, the goddess of memory in Greek mythology, mnemonics are also called memoria technica. The principle is to create in the mind an artificial structure that incorporate unfamiliar ideas or, especially, a series of dissociated ideas by themselves are difficult to remember. Ideally, the structure is designed so that its parts are mutually suggestive."
