Must I use "in" or "after"?

Question

Wait, I'll come back _________(in / after ) two hours time.
Which one can i fill in the blank?

Answer 1

each can fill depending on what you actually mean. to use in means that if you were leaving at 3 you wiil return within the next two hours.meaning that you could return any moment from 3-5 hours.
on the other hand, to use after means that your return will only be after 5 if you left at 3.
but aside that you have a grammatical mistake! 'hours' is a measuring unit for time and everyone knows that and so does not make it right to add 'time' since english grammatical rules does not accept repetition

Answer 2

Both are correct depending on when you are actually going to return... there is actually a third option... Within

'I'll be back in two hours' means you will return two hours from now.

'I'll be back after two hours' means that you will return once the two hours have passed.

'I'll be back within two hours' means that you will return some time between now and two hours time.

Answer 3

after

Answer 4

Depends ... use "in" if you will be back "in" 2 hours. Use "after" if you'll be back in 2, 3, 5, 9, 11 or whatever hours.

Answer 5

after

Answer 6

"Wait, I'll come back in two hours."(Suppose it's now 1 o'clock)
It means I will come back before 3 o'clock.
"Wait, I'll come back after two hours."(Suppose it's now 1 o'clock)
It means I will come back after 3 o'clock.
It depends on situation.

Answer 7

For example the time is 4 p.m..If u use 'in', u mean 'I will come back before 6 p.m...And if u use 'after', u mean 'I will come back after 6 p.m. It can be 7 p.m, 8 p.m, 9 p.m etc..It's up to you.

Answer 8

Spoken English idiom tends to use "in" but actually, "after" makes more sense. It just sounds odd to many of us.

Answer 9

if you are certain that you will come with in 2 hours then use in otherwise after .

Answer 10

You can use either one, they mean the same thing.
