What is the difference between I will finish (in/after) 10 minutes?

Thank you!
In other words:

after 10 minutescan be: 11 minutes later, or tomorrow morningEmotion: smile

You don't want such confusions when say you're scheduling a date.
In -is within the 10 minute window.

After -is beyond the 10 minute window.

Goodman, you say

IN 10 minutes = 7,8,9,10 minutes.

AFTER 10 minues = 11,12,13,14 minutes

AFTER means I will finish 11,12, or 13 minutes ( not within the confine of 10 minutes but really more than 10 minutes) from now!!!!!?

Marius, I did not understand the confusion...i think i need examples.

This is what I understand about IN and AFTER according to Longman Dictionary of American English.

Example 1: I will leave in 10 minutes ( It is 1:00 now and I will leave at 1:10)

Diagram of Example ONE. IN is related to the present point....

_______now10 minutes_x___

Example 2: I will leave after 10 minutes (It is 1:00 now and will leave 10 minutes after we arrive. Thus, I may arrive at the place 1:30..and will leave 10 minutes after I arrive (1:40).

Diagram of Example TWO .

____ now____arrive10 minutes_x___

AFTER implicitly means 10 minutes after his arrival about two points in the future

Please clarify my understanding!!

Now I understand you perfectly Goodman and Marius!

Thanks for your answers...It is soooo easy to understand the difference between in and after the way both of you presented it.

In = within a 10-minute window

After = beyond the 10-,minute window

Yes Marius! It is funny if someone would say to you:

I will see you after 10 minutes LOOOOOOOOOOL.

SO at last, I think I got it!

Ohhh it's such a relief!
Site Hint: Check out our list of pronunciation videos.
Since we are talking about the future (I will finish in/after 10 minutes), I think we need to talk to the correspondent past expressions.

future past

in ago

after before

Examples of the past using (ago/before):


I finished ten minutes ago = within the confine of the past 10 minutes????


I finished before 10 minutes = could mean I finished one hour ago, or even yesterday and thus we should avoid it so as not to confuse anyone!!???
Let me clarify something in case there is a misconception.

Scenario: I am ironing my shirt and I have not been addressed yet for the party. I am running behind schedule to pick up my girl friend who lives a mile from me. So I called her to let her know that I was running late but I would be over her house in 30 minutes.

The 30 minutes is what I thought it would take for me to finish my ironing, getting address and driving over to her house. This is implying it won’t be sooner.

But no one will say “I will meet you after 10 minutes at the lobby”. If you think you can’t make it within 10 minutes, you probably will say “I will meet you at the lobby in half hour”.

Just so it’s clear… I think you got the general idea though.
