DURING est placé avant le nom (during+noun) alors que WHILE se place avant le sujet + verbe (while+subject+verb) Il serait aussi bon de savoir que 'while' est utilisé lorsque l'on parle de deux actions qui se passent en même temps. Je te donne deux exemples pour mieux visualiser la chose : There are a lot of tourists here during the summer. The phone rang while I was watching the TV.

The difference is the context: When you say while it means during the first action another action will be done parallel. for instance "While I was eating my brother brought all the necessary books to begin our training". The word "during" usually is used to show the time in which an action will happen. In this case there are not two actions interconnected each other. For instance "During my holiday I got all the books that I need to begin our training". As you see "holiday" is a time showing event and "while you are eating" is just action.

This is how they are used: While you were away, I fed your dog. While we watched the ball game, I ate popcorn. During the church service, I saw a man falling to sleep. She ate her popcorn during the movie. When you use "while" you say two things were going on...While one thing was happening, something else was happening. When you use "during", there is an event happening when another thing happens, so they are very similar.

For example, 1)'She is reading a book during the day' 2) While she was reading a book he was walking a dog.

The word "during" must be followed by a noun and the word "while" is followed by a clause. Another difference between these two is the word "during" is a preposition and the word "while" is a conjunction. " I ate an apple during the break." " I am eating while watching TV."
