These words are similar in meaning (function), but they are used different grammatically. The main difference between during and while is as follows:
A Noun is Used after 'During'
- During dinner, we talked about school.
- She slept during the movie.
- Do not talk during the test.
A noun always comes after the word 'during'. The word during is a preposition, not a conjunction. You cannot say '
During she.... / During I...' because the preposition is always followed by a noun, not a clause with a subject and a verb.
He made a joke during dinner.
Side Note: We do not use during to say how long something happens. Instead, we use 'for'. For example,
- She slept during the movie. (This is okay -- 'the movie' is not a length.)
- She slept
during two hours. (This is wrong -- 'two hours' is a length of time.)
- She slept for two hours. (Correct!)
A Clause is Used after 'While'
A clause has a subject and a verb (not just a noun). For example,
- While we ate dinner, we talked about school.
- She slept while the movie played.
- Do not talk while students write the test.
The word while is a subordinating conjunction (like the word because or if); it begins a subordinate clause. You need to put a subject and a verb after while to make a sentence, for example: While she studied, he watched TV.
That's it. You can see that the words can be used in a similar way, but the grammar is different.
Do you understand? Let's try some exercises.
