personal pronouns (2): advanced points 429
2 as, than, but and except + me or I
After as and than, object forms are generally used in an informal style. My sister's nearly as tall as me.
I can run Jaster than her.
In a more formal style, subject forms are used, usually followed by verbs.
My sister's nearly as tall as I am.
I can run Jaster than she can.
But (meaning 'except') and except are followed by object forms (see 116, 194).
Nobody but me knew the answer. (NOT N8b6dy Bftt .r ...) Everybody except him can come.
3 Itis/wasmethat.../Iwho...
When a relative clause comes after an expression like It is/was mell, there are
two possibilities:
object form + that (very informal)
It's me that needs your help.
It was him that told the police.
subject form + who (very formal)
It is I who need your help.
It was he who told the police.
We can avoid being too formal or too informal by using a different structure. He was the person / the one who told the police.
4 mixed subject and object: It's for him to decide
Sometimes a pronoun is the object of a verb or preposition, but the subject of a following infinitive or clause. Normally an object form is used in this case.
It's Jor him to decide. (NOT It's }'tJr he t6 tleeitle.)
I think it's a good idea Jor you and me to meet soon.
(Considered more correct than ... Jor you and I to meet soon.) Everything comes to him who waits.
(Considered more correct than ... to he who waits.)
5 inclusive and exclusive we
Note that we and us can include or exclude the listener or reader. Compare: Shall we go and have a drink? (We includes the listener.)
We're goingJor a drink. Would you like to come with us?
(We and us exclude the listener.)
6 us meaning 'me'
In very informal British speech. us is quite often used instead of me (especially as an indirect object).
Give us a kiss, love.
7 Poor you!
You can be modified by adjectives in a few informal expressions such as Poor/CleverlLucky (old) you! (This occasionally happens also with me.) •
