You may have already used some of these common language structures for praising someone’s appearance. Others may be new. For example:

You are / look + adjective
...as in “You are beautiful” and “You look great today!”
A closely related structure simply adds a noun
…as in “You are a beautiful person"

In fact, this structure is also common for praising someone’s abilities, as I will return to shortly.

Other common structures for complimenting appearance are:

I like / love + noun
…as in “I love that bag!” and “I really like your hair.”
And: What a + adjective + noun
…as in “What a fun tie!” and “What a pretty dress!”

​Listen to a short exchange:

Ooh, what a fun tie! Where did you get it?

Oh, thank you! I got it at a shop on 14th Street.

Abilities

We can also compliment someone’s character, abilities or efforts.

Here’s a structure you heard earlier:

You are + adjective + noun
…as in ”You are such a hard worker” and “You really are an amazing cook!”

Note that I added the words “such” and “really.” These adverbs and others, like “very” and “so,” can add strength to compliments.

Next is: You can really + verb
…as in “Wow, you can really sing!”
You are great at + noun / gerund
…as in “You’re great at bringing people together” and “You’re great at math.”
And: You make a / an + adjective + noun
…as in “You make a fine leader” and “You make a very loving partner.”

Listen to a short exchange:

I’m meeting so many interesting people. Sam, you’re great at bringing people together.

That’s a nice thing to say. Thanks! And I’m glad you’re here.

Possessions

Americans also compliment people on their possessions, such as a person’s home (or things inside the home), car, bike, electronics or countless other possessions. We might offer the compliment in any of these ways:

Nice + noun
…as in “Nice bike!” and “Nice phone!”
I love / like your + noun
…as in “I like your dining set” and “I love this painting.”
Or: What a + adjective + noun
…as in “What a beautiful home” or “What a beautiful home you have.”

Listen to a short exchange:

What a beautiful home you have! How long have you lived here?

Oh, thank you! For about three years now.

Receiving compliments

Some people may feel uneasy receiving attention and may deny the compliment in some way. But many receive them easily. A simple “Thank you” with a smile is a gracious way to answer a compliment.

You can also compliment in return by saying, “That’s very kind of you” “How nice of you” or “What a nice thing to say.”

Be sincere

Depending on the social customs where you live, some compliments may be not be received as such. And sometimes, they shouldn’t be. People can make backhanded, inappropriate or insincere comments that they try to pass as compliments.

A “backhanded compliment” is one that may be meant or understood as an insult. Someone might say, for instance, “You look great. Wow, I didn’t recognize you!” This can suggest that the compliment-giver thinks the person rarely looks great.

Other compliments are considered unacceptable. For example, in the U.S., it is often inappropriate to comment on physical appearance in the workplace. This is especially true when a man comments on a woman’s appearance. But it is acceptable for people to compliment each other at work about work.

Another kind of praise is flattery – excessive compliments that are often given in self-interest. An example is praising your supervisor or professor in hopes of gaining better pay or grades. It might work on some people but insincerity can be hard to hide.

So it's always best to follow the first rule of giving compliments: Always be sincere!
