Advice vs advise is a pair that differs by a single letter and by part of speech: advice is the noun for an opinion you give, and advise is the verb for giving it. “She gave me good advice” names the thing; “she advised me to rest” names the action.
Advice vs Advise at a glance

What does advice mean and what does advise mean?
Advice is a noun meaning an opinion or suggestion about what someone should do; advise is a verb meaning to offer that opinion. The Cambridge entry for advice and the Cambridge entry for advise mark this split, and one line shows it: “a word of advice” is a thing you can hold, while “I advise you to wait” is an action you perform.
| Sense | Word | Plain meaning | Example |
|---|---|---|---|
| Opinion offered | advice | A suggestion about what to do | He gave me useful advice. |
| Official guidance | advice | A professional recommendation | The nurse offered advice on diet. |
| Give an opinion | advise | Tell someone what to do | I advise you to wait. |
| Warn against something | advise | Recommend avoiding an act | Doctors advise against too much sun. |
| Formally notify | advise | Inform in business use | We advise you of the change. |
What is the difference between advice and advise?
The difference is part of speech, not meaning alone: advice names the opinion, and advise names the act of giving it. Because the words share a root, a familiar one-letter pair such as abel vs able follows the same logic, where a letter marks a grammar change.
| Test | Advice | Advise |
|---|---|---|
| Part of speech | noun | verb |
| Meaning | the opinion itself | the act of giving it |
| Countability | uncountable, no plural | verb, inflects normally |
| Sound | c as in ice | s as in wise |
| Common pattern | give, take or seek advice | advise someone to do something |
| Quick test | if it names the thing, use advice | if it names the action, use advise |
Choose advice when you could replace the word with suggestion, and advise when you could replace it with recommend.

Which should you use?
Match the word to its slot in the sentence: if it names the thing, use advice; if it names the action, use advise.
| Situation | Use | Example |
|---|---|---|
| Naming an opinion | advice | That is sound advice. |
| Telling someone to act | advise | I advise you to rest. |
| Asking for guidance | advice | She asked for legal advice. |

Register is the second test. Advice appears everywhere, from a chat to a policy document, while advise carries a formal tone in its notify sense, which is why it fills business emails and legal notices. Neither word replaces the other, so the honest limit is this: the noun never takes an object after to, and the verb never sits after give or take.

The bottom line
The advice vs advise choice is settled by grammar rather than meaning, because advice is the noun for the opinion and advise is the verb for giving it. Use the sound test in speech, the c of ice against the s of wise, and the slot test in writing. Remember that advice stays uncountable, so you give pieces of it, and that advise names the person before to.
Frequently asked questions about advice and advise
Is advice a verb or a noun?
Advice is always a noun, and it is uncountable, so you say a piece of advice rather than an advice or advices. The matching verb is advise, which means to give that opinion to someone. The two never swap roles in a sentence.
What is a simple way to choose advice or advise?
Test the slot the word fills. If it follows give, take or seek, and could be replaced by suggestion, use the noun advice. If it is followed by a person or by that, and could be replaced by recommend, use the verb advise. The sound also helps in speech.
Why is advice spelled with c and advise with s?
The spelling marks the part of speech, which is why the pair is easy to mishear. The noun advice ends in c and sounds like ice, and the verb advise ends in s and sounds like wise. This sound-and-letter pairing is the most reliable quick check for learners.
Can advise mean to inform rather than to recommend?
Yes. In business and legal writing, advise often means to notify, as in please advise us of any change. That formal sense keeps the verb role the same, so it still takes a person and a following phrase such as of or that. It never becomes a noun.
