What is the difference between 'complementary' and 'complimentary'?
The Great Vowel Swap: Complementary vs. Complimentary
It is one of the most common spelling dilemmas in the English language. Because these two words sound identical when spoken aloud, they are frequently confused in writing. However, they carry distinct meanings that can drastically change the message you are trying to convey. Let’s break down the difference once and for all.
Definitions
Complementary (with an 'e')
Think of the word complementary as being related to the word complete. When two things are complementary, they combine in such a way as to enhance or emphasize the qualities of each other. They fit together like puzzle pieces to make a whole.
Complimentary (with an 'i')
Think of the word complimentary as being related to a compliment (a kind remark). This word has two primary meanings: first, it refers to expressing praise or admiration. Second, and perhaps more commonly in business, it refers to something given for free, as a gesture of goodwill.
Quick Reference Table
| Word | Root Concept | Primary Meaning | Example Context |
|---|---|---|---|
| Complementary | Complete | Enhancing or matching | Colors, skills, parts |
| Complimentary | Compliment | Praise or free of charge | Reviews, hotel amenities |
Real-World Examples
To master these terms, look at how they function in a sentence:
-
Complementary: "The wine and the cheese were complementary; the sharp cheddar perfectly balanced the sweetness of the dessert wine."
-
Complimentary: "The hotel offered us a complimentary breakfast during our stay, and the manager was very complimentary about our choice of room."
Common Pitfalls
The easiest way to remember the difference is to look at the middle letter. Complementary contains an 'e', just like the word 'enhance' or 'complete'. Complimentary contains an 'i', which you can associate with the 'i' in 'praise' or the 'i' in 'it's free'.
If you are ever in doubt, ask yourself: Am I talking about two things that go well together, or am I talking about a gift or a nice comment? If it's the former, use the 'e'. If it's the latter, use the 'i'.
