another sentence with 'until'

Yes, of course.

Until now [/b] I haven't been able to contact you.

The above sentence means "In the past I could not contact you, but now I can contact you"

Yes it does.

Try using "at this moment" and see if it makes more sense to you, T.

Hi JTT
Until now I haven't been able to contact you.

The above sentence means "In the past I could not contact you, but now I can contact you"

You wrote: Try using "at this moment" and see if it makes more sense to you.

At this moment, I haven't been able to contact you.

Am I doing the correct thing you asked me to? The sentence I posted seems to have a different meaning from the one above. Please let me know where I went wrong.

Many thanks.

"Until now" means "up to the present/ up to the present moment"
