Confusing Words

advice vs advise

These two words look and sound similar but are different parts of speech.

  • advice — Advice' (ending in '-ice') is a noun referring to suggestions or recommendations given to help someone — for example, The marine biologist offered useful advice about how to reduce plastic pollution near the reef.
  • advise — Advise' (ending in '-ise') is a verb meaning to give someone advice or to recommend a course of action — for example, She would advise anyone visiting the reef to wear reef-safe sunscreen.

Memory rule: A helpful trick: 'advice' rhymes with 'ice' and is the thing you give, while 'advise' rhymes with 'wise' and is what you do. Nouns are things; verbs are actions.
