Advice vs. Advise: How to Use These Commonly Confused Words Correctly

Updated May 2026.

Advice and advise are easy to mix up. They look almost identical. They sound different. They mean different things. The first is a noun. The second is a verb. This guide explains the difference. It walks through realistic examples and covers the Latin origin of both words. The most common questions writers have about which form to use are answered at the end.

Quick Answer

Advice (noun).
The guidance, recommendation, or opinion itself. The lawyer's advice was clear.

Advise (verb).
The act of giving guidance or a recommendation. The lawyer advised the client to settle.

Pronunciation cue.
The noun ends in a soft "s" sound (like "ice"). The verb ends in a "z" sound (like "rise").

The simplest test.
Replace the word with "guidance" (noun) or "guide" (verb). If "guidance" fits, the noun is correct. If "guide" fits, the verb is correct.

You give advice. You advise someone.
These two work together but never swap places.

When to Use Advice (Noun)

Use the noun when referring to the guidance itself. It can be the subject or object of a sentence. It takes singular verbs.

As an object.
She gave me good advice about the job offer.
As a subject.
The advice from her mentor changed her career.
With a possessive.
I appreciate your advice on this matter.
Following a verb of seeking or giving.
He sought advice from three different financial planners.

The noun is uncountable in standard English. You don't say "an advice" or "two advices." If you need to count, use a phrase like "a piece of advice" or "two pieces of advice."

When to Use Advise (Verb)

Use the verb when describing the action of giving guidance. It takes a subject (the person giving guidance) and usually an object (the person receiving it).

Present tense.
I advise my clients to read every contract carefully.
Past tense.
The doctor advised her to cut back on caffeine.
Present participle.
She is advising the board on the new policy.
Followed by an infinitive.
The travel agent recommended he book early.
Followed by "that."
The committee recommended that the report be revised.

The Latin Origin of Both Words

The verb followed a similar path. It came from the Old French verb aviser, which itself came from avis. By the 14th century, English had borrowed both forms. The "c" in advice and the "s" in advise reflect a common pattern in English. Several other word pairs follow the same noun-with-c, verb-with-s rule. These include device and devise, practice and practise (in British English), and license and licence (in British English).

Knowing the Latin origin helps remember which form is which. The noun names the thing being seen or judged. The verb describes the act of forming and offering that judgment.

Both Words in Professional Writing

Some contexts use these words more often than others. Three professional fields stand out: law, finance, and healthcare. In each, the verb form appears in formal records of professional guidance. The noun form appears in summaries of recommendations given.

Legal Writing

Lawyers formally counsel their clients. "The lawyer advised the client to accept the settlement" is a standard sentence in case summaries. The corresponding noun phrase is "legal advice." When a lawyer recommends a specific action, courts may later examine that guidance in malpractice cases. The distinction between the verb and the noun matters in legal documents.

Financial Writing

A financial advisor counsels clients on investments, retirement planning, and tax strategy. The advice given is documented in writing for compliance reasons. Sentences like "The advisor recommended diversifying the portfolio" appear in client correspondence, regulatory filings, and dispute records. Using the wrong form can confuse the meaning of a regulatory document.

Medical Writing

A physician counsels patients on treatment options, medication adherence, and lifestyle changes. Medical advice is the documented record of those recommendations. In clinical notes, "the patient was advised to follow up in two weeks" uses the verb form. In a discharge summary, "the patient received clear advice on wound care" uses the noun form. Both forms appear regularly. Both must be used correctly.

Quick Memory Tricks

A few simple tricks make the difference easy to remember.

The "ice" trick.
The noun ends in "ice," like other nouns: ice, dice, mice, rice. All are things, not actions. The noun is a thing.
The "ise" trick.
The verb ends in "ise," like other verbs: revise, surprise, exercise. All are actions. The verb is an action.
The pronunciation trick.
If you can hear a "z" sound at the end of the word in your sentence, you're using the verb. If you hear a soft "s" sound, you're using the noun.
The substitution trick.
Replace the word with "guidance" (noun) or "recommend" (verb). Whichever fits naturally tells you which form to use.

Common Mistakes

These are the errors that show up most often in student writing, business correspondence, and even professionally edited copy.

Using the verb form as a noun.
"I gave him my advise" is wrong. The correct form is "I gave him my advice."
Using the noun form as a verb.
"Please advice me on this" is wrong. The correct form is "Please advise me on this."
Treating the noun as countable.
"She gave me three advices" is wrong. The correct form is "She gave me three pieces of advice."
Mismatching subject and verb form.
"The committee advise the chair" is informal in some British contexts. American English prefers "The committee advises the chair."
Confusing the two in formal writing.
Email subject lines often confuse them: "Please advice" should be "Please advise."

Frequently Asked Questions

What is the difference between advice and advise?

The first is a noun. It refers to the guidance or recommendation itself. The second is a verb. It refers to the action of giving guidance. You give advice. You advise someone. The simplest test is to substitute the word. If "guidance" fits, use the noun. If "recommend" fits, use the verb.

How do I remember the difference?

Use the "ice" trick. The noun ends in "ice," like the nouns ice, dice, mice, and rice. All are things. The verb ends in "ise," like the verbs revise, surprise, and exercise. All are actions. Pronunciation also helps. The noun ends in a soft "s" sound. The verb ends in a "z" sound. If you hear a "z," you're using the verb.

Where do these words come from?

Both come from the same Latin word root. The Latin phrase ad visum meant "according to what is seen" or "in view of." Old French shortened this into avis, meaning opinion or judgment. The English noun came directly from this Old French form. The verb came from the Old French aviser, which itself came from avis. By the 14th century, English had borrowed both forms. The "c" in advice and the "s" in advise reflect a common English pattern that also appears in device versus devise.

Is it advise or advice in an email?

In an email subject line or body, "please advise" is the correct form when asking someone to provide guidance. The verb is used because you're asking the recipient to perform the action of giving guidance. "Please advice" is incorrect because the noun cannot follow "please" as a request to act.

Can advice be used as a verb?

No. The noun form is exclusively a noun. It refers to the guidance itself, not the act of giving it. Sentences like "Please advice me" are incorrect. The correct form is "Please advise me."

What is the past tense of advise?

The past tense is advised. The past participle is also advised. Examples: The lawyer advised the client to settle. The doctor advised against further treatment. The financial advisor had advised the family for over a decade.

Can advice be plural?

No. The noun is uncountable in standard English. You can't say "an advice" or "two advices." If you need to count, use a phrase like "a piece of advice," "two pieces of advice," or "several pieces of advice." The phrase "a word of advice" is also common.

What is the difference between advice and recommendation?

The two terms are similar but not identical. The first tends to be more personal and informal. It often comes from someone with experience or expertise but not necessarily formal authority. A recommendation is more specific and often comes from a position of authority or formal review. A doctor gives medical advice but may write a recommendation for a specialist. A friend gives travel advice but a tour operator gives recommendations.

Are these words spelled differently in British versus American English?

No. Both forms are spelled the same in both varieties. The "s" spelling is standard in both. This differs from some related word pairs where British English uses different spellings. For example, British English distinguishes between practice (noun) and practise (verb). American English uses practice for both. This pair follows the same pattern in both varieties of English.

Is it correct to say good advice or strong advice?

Both are correct. "Good advice" is the most common phrase. It means helpful or sensible guidance. "Strong advice" carries a slightly different meaning. It suggests urgent or emphatic guidance, often when the speaker feels strongly about the recommendation. Other common adjective combinations include sound advice, helpful advice, professional advice, free advice, and unsolicited advice.

More Commonly Confused Words

These two words are part of a broader pattern in English: noun-verb pairs where one form ends in "c" and the other ends in "s." Other examples include device and devise, prophecy and prophesy, and (in British English) practice and practise. Each pair follows the same rule. The noun ends in "c," the verb ends in "s."
