Being and Been

The word 'been' is always used after have (in any form of, e.g. has/ had/ will have). The word 'being' never should be used after have. It is used after to be (in any form, e.g. is/ was/ were). Lets see some examples to find the difference between been and being.

• (have + been + present participle) = have been doing
• (is + being + past participle) = is being done

Examples

• He has been doing it for over two hours.
• He has being done. (This sentence is wrong. being cannot use after has or have).
• He is being done.
• They have been playing cricket for six hours.
• John's computer is being sold next month.

Noun

You can use being as a noun. Lets see some examples. 

• A human being
• A stranger being came with his space ship.

Gerund

being can also be a gerund (which is a type of noun).

• Does she like being so ignorant?
• We were lost the game by his being so clumsy.
