How to Pay Someone a Compliment in English:-

One of the nicest things you can do in any language is to compliment someone. You might want to compliment someone on what they did, how they look or what they have. Here are forms and phrases to compliment others in English. I've arranged compliments into complimenting ability, complimenting looks, and complimenting possessions in both formal and informal situations.
Complimenting Ability
Use these phrases to compliment someone on an ability they have. If you'd like to learn something from the person about his / her ability, start with a compliment. The person will probably help you learn more and be happy to talk about how to do it.
Formal
If you don't mind my saying, you are a(n) excellent / outstanding / superb + (noun phrase)
I must say you really know how to + (verb)
You are a fine + (noun phrase)
What a(n) excellent / outstanding / superb / + (noun phrase) you are!
I admire your ability to + (verb)
Mr. Smith, if you don't mind my saying, you are an excellent public speaker.
I must say you really know how to paint.
I admire your ability to think on your feet.
Informal
You're great at (verb + ing)
You can really (verb)
Wow, I wish I could (verb) as well as you!
You're an amazing / awesome / incredible + (noun phrase)
Wow! You're great at skiing!
You can really cook. This is amazing food!
You're an awesome student.
Complimenting Looks
Use these phrases to compliment someone on how they look. I've divided this into two categories: for women and for men. It's important to use the right language for the situation. If you pay someone a compliment on their looks in the wrong way, it's possible that your compliment will not be accepted.
Formal
Notice how we ask permission to pay compliments on good looks in formal English. This is to ensure that no one gets the wrong idea about your intention.
May I be so bold as to compliment your + (dress / hair / outfit / etc.)?
You are looking beautiful / handsome today.
May I pay you a compliment? You really look beautiful / handsome / elegant /etc. today.
I hope you don't mind, but you are looking beautiful / handsome today.

Complimenting Possessions
Use these phrases to compliment someone on something they have. People are often proud of their possessions, especially major objects such as a house, a car, or even a stereo system. Complimenting someone on a nice possession is a good way to make small talk.
