I will come in ten days.
Some people say ,"in ten days"means "after the tenth day"in this case.
Is it true?I can not grasp this.
I need help.
Saying "I will come in ten days." is not quite as clear as stating a specific date.
However, if today is the 1st day of the month, then saying "I will come in ten days" would usually be understood as "I will come on the 11th."
Let's say someone leaves on a business trip at 6:00 a.m. on the first of the month and the scheduled return is 9 p.m. on the 10th of the month. It's entirely possible that this person might say "I'll be back in 10 days". Whether you think it's right or wrong for the person to say that is irrelevant. The fact remains that it is always clearest to state a date of arrival or return.
Mrs or Mrs and Mses ,I have looked through all your views above,but I am still unclear abut why it is such a case.
I do not find a sense of "in" that it means "after" in several dictionaries.
In dictionaries,it is only explained as "within or during a period".
What I want is just a logic and reasonable explanation about relation between
"in" and "after".
I really cannot connect them up at all.
if I want to mean: I will come back on any day of that ten days,
can I say"I will come back in ten days"?
