Grammar Rules
Grammar Rules & Mechanics
Understanding the distinction between a preposition and a conjunction is the key to never confusing 'during' and 'while' again.
Noun vs. Clause
'During' is a preposition and requires a noun object. 'While' is a conjunction and requires a clause (subject + verb).
- Correct: I fell asleep during the movie.
- Incorrect: I fell asleep while the movie.
- Correct: I fell asleep while I was watching the movie.
- Incorrect: I fell asleep during I was watching the movie.
'The movie' is a noun, so the preposition 'during' is correct.
'I was watching' is a clause, so the conjunction 'while' is correct.
Omitting the Subject
Sometimes you can drop the subject and the 'be' verb after 'while' if it is the same as the main clause subject. You cannot do this with 'during'.
- Correct: While waiting for the bus, I read a book.
- Incorrect: During waiting for the bus, I read a book.
You can use 'while' + present participle (-ing). 'During' cannot be followed by a verb ending in -ing.
Contrasting (Whereas)
When meaning 'whereas' or 'although', only 'while' can be used.
- Correct: While I like apples, my brother likes oranges.
- Incorrect: During I like apples, my brother likes oranges.
Here, 'while' means 'whereas'. 'During' has no contrasting function.
Noun Forms
'While' can function as a noun meaning a period of time. 'During' cannot be a noun.
- Correct: I haven't seen him in a while.
- Incorrect: I haven't seen him in a during.
'A while' is a noun phrase meaning 'a period of time'.
When to Use "During"
Specific scenarios where 'during' is the correct choice. It is a preposition used to indicate that an event happens within the timeframe of a noun (an event, a period, or an activity).

Use 'during' before a noun phrase to show that something happened within the timeframe of that event.
Example: Please keep your phones on silent during the meeting.

Example: The town attracts many tourists during the summer.
