Memory system

A mnemonic (RpE: /nəˈmɒnᵻk/,AmE: /nɛˈmɑːnɪk/, the first "m" is silent) device, or memory device, is any learning technique that aids information retention in the human memory. Mnemonics make use of elaborative encoding, retrieval cues, and imagery as specific tools to encode any given information in a way that allows for efficient storage and retrieval. Mnemonics aid original information in becoming associated with something more meaningful—which, in turn, allows the brain to have better retention of the information. 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.
