COMPLIMENTARY VS. COMPLEMENTARY

What’s the difference between complimentary and complementary?

Complimentary is an adjective that can describe something intended to be a compliment—a comment that expresses praise or admiration of someone (as in a complimentary remark). It can also be used to mean that something is given for free, as in I hope we get complimentary snacks on this flight. Complementary is an adjective used to describe something that complements something else—goes along with it and serves to make it better or complete it (as in complementary colors).

Since the primary senses of both words are generally used in positive contexts, it can be easy to confuse them.

The easiest way to remember the difference is that complementary often involves something that completes something else, and complete also starts with c-o-m-p-l-e. On the other hand, you can remember that complimentary is spelled with an i because compliments are something that I like to get (and give). Nice shirt, by the way.

Here’s an example of complimentary and complementary used correctly in the same sentence.

Example: Sometimes, when the chef overhears complimentary feedback about a dish, she sends out a complimentary bottle of wine—one that’s complementary to the rest of the meal, of course.
