Mnemonic
A mnemonic (RpE: ,AmE: the first "m" is silent), mnemonic device, or memory device is any learning technique that aids information retention in the human memory. Mnemonics aim to translate information into a form that the brain can retain better than its original form. Even the process of merely learning this conversion might already aid in the transfer of information to long-term memory. Commonly encountered mnemonics are often used for lists and in auditory form, such as short poems, acronyms, or memorable phrases, but mnemonics can also be used for other types of information and in visual or kinesthetic forms. Their use is based on the observation that the human mind more easily remembers spatial, personal, surprising, physical, sexual, humorous, or otherwise "relatable" information, rather than more abstract or impersonal forms of information.
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.
