Compliment and complement are easy to mix up because they sound the same. Their meanings, however, are different.
Compliment means praise or a kind remark. Complement means something that completes, improves, or goes well with something else.
Compare these sentences:

The jacket complements my outfit.
In the first sentence, someone is giving praise. In the second, one thing works well with another.
The same difference appears in complimentary and complementary, so understanding the two base words makes those forms much easier too.

What Are the Four Types of Complements?
In English grammar, complement can refer to a word or phrase that completes the meaning of another part of a sentence.
Common categories include:
- Subject complement — gives information about the subject.
- Object complement — gives information about the object.
- Adjective complement — completes the meaning of an adjective.
- Prepositional complement — completes the meaning of a preposition.
For example:

Captain is an object complement because it gives more information about James.
An adjective complement can follow an adjective:

Of her team completes the meaning of proud.
A prepositional complement can complete a preposition:

The sky completes the preposition at.
Grammar books may classify complements in slightly different ways, but the main idea is the same: a complement adds information needed to complete the meaning of another part of the sentence.
