Quick Answer

The difference between complement and compliment is their meaning.

Complement means to complete, improve, or match something well.
Compliment means to praise or say something nice about someone.

Although the two words are pronounced almost the same, they are never interchangeable because they have different meanings.

Examples:

The red tie complements his black suit perfectly.
Fresh herbs are a perfect complement to the soup.
She gave me a wonderful compliment about my presentation.
I thanked him for the kind compliment.

Pronunciation of Complement or Compliment

Both complement and compliment are pronounced almost identically:

Complement: KOM-pluh-ment (/ˈkɒm.plɪ.mənt/ UK, /ˈkɑːm.plə.mənt/ US)
Compliment: KOM-pluh-ment (/ˈkɒm.plɪ.mənt/ UK, /ˈkɑːm.plə.mənt/ US)

Because they sound the same, they are called homophones—words that share the same pronunciation but have different meanings and spellings.

When speaking, listeners understand the correct word from the sentence’s context.

Examples:

“Your smile complements your personality.”
“Your smile is a lovely compliment to everyone around you.”

Easy Trick to Remember Complement or Compliment

A simple memory trick can help you remember the difference forever.

Remember Compliment = “I” = Praise

The word compliment contains the letter I, just like I admire you or I praise you. If someone says something kind, use compliment.

Example:

She gave me a compliment on my new haircut.

Remember Complement = “E” = Enhance

The word complement contains the letter E, which can remind you of enhance or complete. If one thing improves or completes another, use complement.

Examples:

The blue curtains complement the white walls.
A healthy diet complements regular exercise.

Full complement or compliment

The correct word depends on the meaning of the sentence. Full complement means the complete number of people or things needed for a group, team, or organization.

Full compliment is usually incorrect unless you mean a complete expression of praise, which is much less common.

In most everyday writing, the correct phrase is full complement. Remember, complement relates to completing something, while compliment relates to praise.

Examples:

The ship sailed with its full complement of crew members.
The hospital has a full complement of medical staff.
Our team reached its full complement before the tournament.
The airline hired a full complement of flight attendants.

Complement meaning

A good complement is something that matches, improves, or completes another person or thing. It does not mean praise—that would be a compliment.

The phrase is commonly used to describe people, foods, colors, skills, or objects that work well together.

When one thing makes another more effective or attractive, it is a good complement. This meaning is the same in both British and American English.

Examples:

Fresh bread is a good complement to homemade soup.
Her communication skills are a good complement to his technical expertise.
The blue curtains are a good complement to the white walls.

Use compliment and complement in a sentence
