to which

[navi tasan]

Is this sentence correct:

1-"There was a party to which he was invited and he didn't go."

[Red5]

The "to which" part sounds fine to me, it's the "and he didn't go" bit that sounds a little odd IMO. I would remove the word "he".

BTW, Using "to which" sounds very formal to my ears.

Thanks Red.
Actually I didn't intend to put in the second "he". It was a typo!
As for for the "to which" being formal, how about these ones:
2-There was party he was invited to and/but didn't go.
3-There was party he was invited to and/but didn't go to.
I don't know whether one need the last "to" or not.

[Red5]

You would probably hear people leave out the last "to" in speech, but I'd bet that grammatically the "to" is required. That particular discussion I'll leave for the others here.

but he didn'tgo to- drop the 'to'

Thanks Red5 and Tdol.
