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

Advice and advise are easy to mix up. They look almost identical. They sound different, and 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.

Advice vs. Advise: At a Glance

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 advised him to book early.
• Followed by "that."
  The committee advised that the report be revised.

The Latin Origin of Both Words

Both words trace back to the same Latin root. They come from ad ("to") combined with visum, a form of the verb videre ("to see"). The sense of "seeing" became the sense of "forming a view" or "holding an opinion." The words reached English through Old French avis, meaning opinion or judgment, which grew out of the phrase that translates roughly as "it seems to me." The English noun came directly from this Old French form.

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, where a noun ends in "c" and its matching verb ends in "s." The clearest example of the same pattern is device (noun) and devise (verb).

Knowing the origin helps you remember which form is which. The noun names the opinion or judgment itself. 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 advises 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 advised the client to diversify 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."

More Commonly Confused Words
