Mnemonic — Meaning, Definition & Examples

What does mnemonic mean?

A mnemonic is anything that makes information easier to remember by linking it to a simpler pattern. It can be an acronym (each letter starts a word you need to recall), a rhyme, an image, or a short phrase. The word works as both a noun (“a mnemonic”) and an adjective (“a mnemonic device”).

Mnemonics work because the brain recalls structured, vivid, or rhyming material far more easily than a plain list.

Pronunciation and part of speech

Mnemonic is pronounced nih-MON-ik (/nɪˈmɒnɪk/). The leading “m” is silent — say it as if it began with “n.” It is most often a noun, and also an adjective in the phrase “mnemonic device.”

Common mnemonic examples

• ROYGBIV — the colors of the rainbow. • PEMDAS — the order of operations in math. • “Thirty days hath September…” — the length of the months. • RAVEN — Remember, Affect is a Verb, Effect is a Noun (see our affect vs effect guide).

Synonyms

Synonyms: memory aid, reminder, aide-mémoire, learning device, memory trick.

Word origin

Mnemonic comes from the Greek mnēmonikos, “of memory,” related to Mnemosyne, the Greek goddess of memory. The silent “m” is a leftover from that Greek spelling.

Remember the grammar rules too
