The words ‘being’ and ‘been’ are sometimes confused. As a rule the word ‘been’ is always used after ‘have’ whereas ‘being’ is never used after ‘have’. It is used after ‘be’.
'Been' is the past participle of the verb 'be' and is usually used with the perfect aspect with ‘have’ in all its forms i.e. had and has

When we are writing it is very easy to get confused by 'it's' or 'its'. Here is an explanation that may help avoid confusion:
'It's' is short for 'it is' or 'it has' and this is the rule. If you can't expand 'it's' to 'it is' or 'it has' then you're using 'its' when you shouldn't and that is wrong.
It's been raining all week and now it's starting to snow. (it has – it is)
It's been a very difficult year for me. (It has)
There is often confusion over the words ‘effect’ and ‘affect’. In order to understand the difference it is important to remember that ‘effect’ is a noun whereas ‘affect’ is a verb.

Affect is a verb meaning 'to transform' or 'to change'.
Did the economy affect your business?

The word may is used to denote permission:

Advice and advise are normally confused. 'Advice' is a noun and it means 'a suggestion' or 'a beneficial course of action'. Advice is a non-count word so it has no plural and can't be used with the indefinite article:

He gave me a good piece of advice. NOT He gave me a good advice.
'Advise' is a verb and it means 'to give advice'
