Compliment or Complement: What’s the Difference?

Compliment or Complement: Compliment and complement are two of the most commonly confused words in English. They look nearly identical, sound the same in many varieties of English, and can both appear in positive contexts. Yet their meanings are different.

The simplest rule is:

Compliment = praise or admiration
Complement = complete, enhance, or go well with something

For example:

• She complimented me on my presentation. → She praised me.
• The illustrations complement the article. → The illustrations enhance the article.

The related words complimentary and complementary create another layer of confusion. One can mean free or praising, while the other describes things that work well together. The pair also appears in expressions such as “compliments of” and “full complement,” while complement has a specific meaning in English grammar.

So, which spelling should you use? The answer depends entirely on what you mean.

Compliment or Complement: Which One Is Correct?

Both compliment and complement are correct English words. Neither spelling is universally correct; you choose one according to the meaning of the sentence.

Word	Main meaning	Example
Compliment	Praise or admiration	She gave me a compliment.
Complement	Something that completes or enhances	The sauce is a perfect complement to the dish.

Use compliment when someone expresses praise, approval, admiration, or respect.

Use complement when one thing completes, enhances, balances, or works well with another.

Compare these two sentences

He complimented her on her new hairstyle.

He praised her hairstyle.

Her new hairstyle complements her face.

The hairstyle enhances or suits her face.

The meaning—not the sound—determines the spelling.

What Does “Compliment” Mean?

Compliment is a noun and a verb associated with praise, approval, admiration, or respect.

Compliment as a noun

A compliment is a positive remark or expression of praise.

Examples:

• She gave me a lovely compliment.

• That was one of the nicest compliments I have ever received.

Examples:

A useful sentence pattern is:

What Does “Complement” Mean?

Examples:

In these examples, complement does not mean praise. It refers to something that adds to another thing in a way that makes the combination more effective or pleasing.

Complement has another important meaning: the full number or quantity required or available.

For example:

• The photographs complement the article.

A particularly useful expression is:

Complimentary vs. Complementary

The adjective forms are another major source of confusion.

What Does “Complimentary” Mean?

Complimentary is related to compliment.

It has two especially common meanings:

1. Expressing praise or approval
2. Provided free as a courtesy

For example:

She was very complimentary about my work.

Here, complimentary means praising.

But:

The hotel offers complimentary breakfast.

Here, complimentary means free.

This second meaning is especially important because complimentary does not always mean “praising.”

What Does “Complementary” Mean?

Complementary is related to complement.

It describes things that combine well, complete one another, or enhance one another.

Examples:

The two colors are complementary.

Their skills are complementary.

The flavors have complementary qualities.

Complimentary vs. Complementary Table

Word	Meaning	Example
Complimentary	Praising	The review was complimentary.
Complimentary	Free	The hotel provides complimentary breakfast.
Complementary	Working well together	Their skills are complementary.
Complementary	Completing or enhancing	The colors are complementary.

Easy memory rule

Complimentary → praise or free

Complementary → completing, matching, or enhancing

Compare:

She made a complimentary remark about my work.

She praised the work.

The two skills are complementary.

The skills work well together.

What Does “Compliments Of” Mean?

You may have seen the expression:

Compliments of the restaurant

Here, compliments of is a conventional expression meaning that something is provided by someone, often free of charge or as a courtesy.

For example:

The drinks were compliments of the restaurant.

This means the restaurant provided the drinks.

Another example:

A gift, compliments of the company.

The company provided the gift.

Do not confuse this expression with complementary. The expression compliments of uses the spelling associated with compliment.

What Does “Full Complement” Mean?

The expression full complement has nothing to do with praise.

A full complement means the complete number or quantity required or available.

For example:

The ship left the harbor with its full complement of crew.

The phrase refers to the complete number of crew members.

Another example:

The school now has a full complement of teachers.

The school has the complete number of teachers it requires.

This meaning is easy to miss if you learn only the basic rule “compliment = praise, complement = enhance.”

What Is a Complement in English Grammar?

Complement is also an established grammatical term.

In English grammar, a complement is a word or phrase that completes or adds important information about another part of a sentence.

For example:

Sarah is a doctor.

A doctor is a subject complement because it identifies or describes the subject, Sarah.

Another example is:

They elected Maria president.

President functions as an object complement because it provides information about the object, Maria.

The grammatical meaning is completely separate from the everyday meaning of “something that matches.”

Subject complement

A subject complement follows a linking verb and describes or identifies the subject.

Examples:

James is a teacher.

The soup smells delicious.

Her idea became a success.

Object complement

An object complement provides information about or describes the direct object.

Example:

They painted the door red.

The committee elected Sarah chairperson.

So, complement is not limited to colors, food, clothing, and design. It is also an important grammatical concept.

Why Are Compliment and Complement Confused?

There are several reasons these words cause problems.

1. They look almost identical

The main spelling difference is one vowel:

• compliment
• complement

That small difference is easy to overlook when writing quickly.

2. They sound the same in wide varieties of English

In many varieties of English, compliment and complement are pronounced alike.

That makes the distinction particularly difficult in listening and conversation because the spelling cannot be heard.

3. Both words can be nouns and verbs

Compare:

She gave me a compliment.

She complimented me.

And:

The sauce is a complement to the meal.

The sauce complements the meal.

Their similar grammatical flexibility adds to the confusion.

4. Both can occur in positive contexts

A compliment is positive because it expresses praise.

A complement can also be positive because something can enhance another thing.

For example:

He gave me a compliment.

versus:

His skills complement mine.

Both sentences describe something positive, but the underlying meanings are different.
