Advice is a noun meaning a suggestion or guidance. Advise is a verb meaning to give that suggestion. You give advice, but you advise someone. The last letter changes the word’s job in a sentence and its pronunciation: advice ends with an /s/ sound, and advise ends with a /z/ sound.

This distinction appears in everyday conversations, school assignments, business emails, and professional writing. Once you recognize whether your sentence needs a thing or an action, choosing the correct spelling becomes much easier.

Advice is the guidance you receive

When you ask somebody what you should do, the suggestions they offer are advice. You can ask for advice, receive advice, ignore advice, or follow advice. In all four examples, the word refers to information or recommendations rather than the action of delivering them.

• “I asked my teacher for advice before the exam.”
• “Her financial advice helped me prepare a budget.”
• “Thank you for your honest advice.”
• “He ignored his friend’s advice about the weather.”
• “The counselor offered helpful advice about applications.”

Notice how adjectives fit naturally before the noun: useful advice, practical advice, unsolicited advice, or thoughtful advice. You cannot substitute advise in those expressions because it is not a noun in standard modern usage.

Advise is the action of recommending

The verb advise describes what a person does when they offer guidance. It can also mean giving someone official information. A teacher may advise a student to revise an essay; a company may advise customers of a change in opening hours.

Here are natural sentence patterns:

1. “I advise you to read the instructions.”
2. “The doctor advised him to rest.”
3. “She advises new employees on office procedures.”
4. “Please advise us of any changes.”
5. “My mentor advised me against rushing the decision.”

Unlike the noun, the verb changes form. Advises is a present-tense form used with he, she, or it. Advised is the past tense and past participle. Advising is the present participle. Those changes tell readers when the action happened or how it relates to the subject.

A quick grammar test

Try replacing the uncertain word with suggestion or recommend. If suggestion works, you probably need the noun advice. If recommend works, the verb advise is likely correct.

“Can I get your suggestion?” makes sense, so “Can I get your advice?” is correct. “I recommend that you leave early” makes sense, so “I advise you to leave early” is correct. This method is more reliable than guessing from the sentence’s tone.

Another clue is the word before it. Expressions such as some advice, good advice, and your advice clearly need a noun. Expressions such as will advise, can advise, and please advise clearly need the base form of a verb.

Please advise or please advice?

“Please advise” is correct. It is a request for someone to provide guidance or information. “Please advice” is incorrect because please needs the verb in that construction.

In a business email, however, “Please advise” on its own can sound abrupt or unclear. A more specific request is often more helpful:

The last version asks for the actual action rather than general guidance. Good professional writing favors clarity over formal-sounding phrases when the recipient already knows what you need.

Why an advice and advices are usually wrong

Advice is an uncountable noun in ordinary English. That means you do not usually say “an advice” or “three advices.” Say “some advice,” “a piece of advice,” or “three pieces of advice” instead.

Compare these examples:

• Incorrect: “She gave me an advice.” Correct: “She gave me a piece of advice.”
• Incorrect: “I received several advices.” Correct: “I received several suggestions” or “several pieces of advice.”
• Incorrect: “Can you give me many advices?” Correct: “Can you give me some advice?”

Cambridge Dictionary’s advice or advise grammar entry confirms this noun-and-verb difference and the uncountable use of advice. In specialized commercial or legal contexts, advices can occur with technical senses, but it is not the standard plural for everyday recommendations.

Pronunciation helps you remember the spelling

The two words sound different even though their spellings are close. Advice is pronounced approximately “ad-VICE,” with the final sound in ice. Advise is approximately “ad-VIZE,” ending with the voiced /z/ sound found in rise. Both have the stress on the second syllable in common American pronunciation.

Try saying “I need advice” and “Please advise me” aloud. The sound contrast makes the grammar distinction easier to remember. Merriam-Webster also explains the different final consonants in its advise versus advice usage guide.

Common mistakes in real sentences

A wrong choice may be understandable to the reader, but correcting it makes your message look more careful. Notice which part of speech each sentence needs.

The misspelling adviced is especially easy to make. Because the base verb is advise, its past-tense spelling is advised. The /z/ sound remains in speech even when the word gets an -ed ending.

Advice, adviser, and advisor

A person who gives advice may be called an adviser or an advisor. Both spellings are used in American English, although some job titles and organizations prefer one. An academic adviser and a financial advisor may have different duties, but the spelling variation alone does not establish the person’s qualifications.

The verb is still advise, regardless of which occupational spelling you use. Someone can advise students and serve as their adviser. In the same sentence, students can thank that adviser for their advice. Keeping the noun, verb, and person distinct helps in longer paragraphs.

Check your understanding with five examples

Choose either advice or advise for each blank. Look at the grammar around the missing word before checking the answer.

1. My coach gave me helpful ______ before the match.
2. Could you ______ me on which form to complete?
3. She will ______ the committee tomorrow.
4. His ______ was to practice a little every day.
5. We appreciate your ______ about the proposed schedule.

Remember the simplest contrast: advice is what you get, and advise is what someone does. When a sentence feels uncertain, test whether you could use suggestion or recommend. That one choice will solve most everyday mistakes.
