FUN vs FUNNY

Language as a communication system varies from country to country. It may be quite difficult for one to learn a new language which greatly differs from one's first language. In my opinion, the most difficult aspects of learning a new language are pronunciation, grammar and vocabulary. We, here, are going to talk about the difference between FUN and FUNNY.

FUN

-Fun is normally an uncountable noun. It can be used after 'be' to say that things or people are enjoyable or entertaining. For instance:
We had a lot of fun at Eddie's party.
I decided to learn French, just for fun.
She's very lively and full of fun.
Peter and John are a lot of fun.

In informal English, 'fun' can also be used as an adjective as illustrated in the examples below:
She's really fun to be with.
That was a real fun party.
This game looks fun!
There were a lot of fun things for young people to do there.

FUNNY
'Funny' is an adjective, and is used to say that something makes you laugh or amuses you. For instance:
Why are you wearing that funny hat?
I was really embarrassed, but then I saw the funny side of it.
That's the funniest thing I've ever heard.

HELP: Note that 'funny' does not mean 'enjoyable':
The party was great fun.
But one can't say - 'The party was very funny.'

Funny can also be used to refer to something that is difficult to explain or understand. It can mean strange or peculiar:
That's funny- he was here a moment ago and now he's gone.
The engine is making a very funny noise.
A funny thing happened.

Funny can also be used in a humorous way showing lack of respect for somebody:
Don't you get funny with me!
