1) I consider her as my best friend.
2) I consider her to be my best friend.
3) I consider her my best friend.
I'd really like to know which one is grammatically correct.
And if all the sentences are correct, which one is the most frequently used?
Thank you in advance.
Because we don't say "I consider something as ..."
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Thank you very much.
