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.

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

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.

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.

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

The sauce is a complement to the meal.

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