The prepositions during, for, since and while are often used with time expressions; they are used to say how long something took. However, we use them with different time words. Let's take a look at the difference in usage between the prepositions.
How to use during
During is a preposition, which is used before a noun (during + noun) to say when something happens. Sometimes it means for all the time, and sometimes it means for just a part of the time. It does not tell us how long it happened.
For example:
· "Nobody spoke during the presentation."
· "We get plenty of snow here during the winter."
· “My grandmother worked in the USA during the war.”
· “I heard a strange noise during the night.”
How to use while
When is used to talk about two things that are happening at the same time. The length of time is not important. Remember that while is used with a subject and a verb (while + subject + verb).
For example:
· "The phone rang while I was watching TV."
· "I met him while we were studying in the library."
How to use for
For is a preposition which is used with a period to say how long something goes on. This preposition is mainly used when we say the number of hours, days, months, etc. We also use it in expressions like “for ages” and “for a long time”.
For example:
· "Simon has been sleeping for 8 hours."
· "We waited for 30 minutes outside your house."
· “I’m going to live in France for 2 years.”
· “I sat down for 5 minutes.”
· “I’ve worked here for 3 months.”
How to use since
We use since when we say when something started (for instance when stating the starting point: Tuesday, 2008, midnight). We only use since with perfect tenses – when something started in the past and is still true now.
For example:
· I've lived here since October.
· I'd known Sam since 1999.
· I’ve been working here for 6 years.
· I’ve been working here since I left university.
