During, for, while

B1 Intermediate

Learn how to use during, for, and while to describe when things happen and how long they last.

Overview

These three words all relate to time, but they function differently in a sentence. During and for are prepositions followed by nouns, while while is a conjunction used to connect two clauses.

  • During tells us when something happened within a period of time.
  • For tells us how long something lasted (duration).
  • While describes two actions happening at the same time.

During vs. For vs. While

Use during with a noun to name the event itself. Use for with a number and a time unit to measure the length. Use while when you want to include a subject and a verb.
