# Mnemonic — Meaning, Definition & Examples

> A mnemonic (noun, pronounced nih-MON-ik — the first m is silent) is a device that helps you remember something: a rhyme, acronym, pattern, or phrase. “ROYGBIV” for the colors of the rainbow and “PEMDAS” for order of operations are classic mnemonics.

## 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

A lot of writing mistakes are really memory slips — affect vs effect, its vs it’s, who vs whom. Our writing guides pair each rule with a quick mnemonic, and Humanit’s free grammar checker catches the slip in your own text and explains the fix.
