The Critical Distinction

These homophones trip up even seasoned writers, yet their meanings diverge significantly. Compliment involves praise and admiration, while complement involves completion and enhancement. Master this difference, and your professional writing will shine.

Compliment: The Art of Praise

A compliment represents verbal or written appreciation—a social nicety that acknowledges excellence, beauty, or achievement. Whether functioning as a noun or verb, it always carries positive sentiment.

As a verb:

• The director complimented the cast on their outstanding performance.
• I must compliment you on your excellent choice of venue.

The Special Case: Complimentary

When something is complimentary, it's offered free of charge:

• The hotel provides complimentary breakfast
• Complimentary tickets were distributed to employees
• Enjoy our complimentary Wi-Fi service

Memory Technique

Think: Compliment = I like it! The "i" connects to expressing appreciation.
