The use of for, during and whileTHE USE OF FOR, DURING AND WHILE

The prepositions during, for, and while are often used with time expressions

How to use for?

For is a preposition which is used with a period to say how long something goes on, It answers the question : How long?for twenty minutes for a weekfor a long time for a yearFor example:"Simon has been sleeping for 8 hours.""We waited for 30 minutes outside your house."

How to use during

During is a preposition which is used before a noun (during + noun) It means 'throughout the period' or 'in the course of' an action or event. during thematch during the warduring the weekend

I fell asleep during the film because it was so boring. (The sleeping happened at the same time as the film.)

Notice that during is followed by a noun, which often represents an activity(during + the film)."Nobody spoke during the presentation."The bank was robbed during the night

Remember You cannot use during to say how long something continues.Incorrect= It snowed during 3 nights correct = It snowed for 3 nights

How to use while

While is used to talk about two things that are happening at the same time. The length of time is not important. It is very similar to during, but it is followed by a sentence (while + subject + verb...), so they are not interchangeable. For example:1. Stan: When did you lose your credit cards?Mark: I think it was while I was shopping in El Corte Ingls.2. "The phone rang while I was watching TV."3. "I met him while we were studying in the library."

IT IS OFTEN POSSIBLE TO DROP SUBJECT + BE : I generally listen to music while driving to work.Sam twisted his ankle while playing tennis.WHILE CAN ALSO BE A NOUN WHICH MEANS 'A PERIOD OF TIME'.I spoke to the neighbor for quite a while yesterday.It's been a while since I read that book.
