1. ## for

Hello,

In these cases, is "for" always necessary?

=> He is here FOR 25 days.

=> He's going to stay FOR 25 days.

Thanks a lot.

Are you sure the first sentence is OK?

I'd say "He has been here for 25 days." "He is going to stay here for 25 days" is ok and for refers to a period of time(25 days).

4. ## Re: for

Both sentences are correct as written. "He is here for 25 days" is not the same as "he has been here (for) 25 days." If I travel to a place with the intention of staying for 25 days, I can say, early in that trip, "I'll be here (for) 25 days," or "I'm here (for) 25 days." I think there is an implied "scheduled to be" between "I'm" and "here."

You could omit "for" in either case, but it's better if you leave it in.

[QUOTE=Heterological;618463]Both sentences are correct as written. "He is here for 25 days" is not the same as "he has been here (for) 25 days."

And what's the difference?

6. ## Re: for

"He is here (for) 25 days" means that he is scheduled to be here for a total of 25 days. He may have just arrived yesterday, or a week ago; all we know is that the total duration of the trip will be 25 days.

"He has been here (for) 25 days" means that 25 days have passed since his arrival. He may plan to stay longer, or he may be getting on a plane to leave as we speak. All we know is that he has already spent 25 days here.

7. ## Re: for

Is "for " necessary in the following case?: "He can stay (for?) months without talking to anyone.

Thank you.
