please could you tell me whether the second sentence is correct in the context?
I am waiting for her, she should already be here but she is not.
She was to be here 10 minutes ago.
Thanks a lot,
The second sentence is absolutely correct- the verb "to be" is used in its modal meaning when we deal with some arrangements or schedule. I.e., they have agreed to meet at a certain time, e.g. at 2pm, now it's 2.10 and she is still not there.
All the best,
