Mnemonic

The word "mnemonic" is derived from the Ancient Greek word μνημονικός (mnēmonikos), meaning "of memory, or relating to memory" and is related to Mnemosyne("remembrance"), the name of the goddess of memory in Greek mythology. Both of these words are derived from μνήμη (mnēmē), "remembrance, memory". Mnemonics in antiquity were most often considered in the context of what is today known as the art of memory. https://en.wikipedia.org/wiki/Mnemonic
