Learn English – “In the next ten minutes” vs. “for the next ten minutes”

meaningprepositionsword-choice

  1. I am planning to do it in the next ten minutes.
  2. I am planning to do it for the next ten minutes.

Do the two sentences mean the same thing? I am sure using for is correct, but I want to know whether using in changes the meaning.

Best Answer

No, they don't necessarily mean the same thing.

  • I'm planning to do it in the next 10 minutes.

    suggests that you will do something that will probably take much less than 10 minutes to complete, e.g., throw out the garbage.

  • I'm planning to do it for the next 10 minutes.

    means that you will spend the next 10 minutes doing something, e.g., exercising or practicing your guitar or doing your homework.

Grammatically, both are correct. Semantically, however, they are different.
