Lesson 0050

Let’s compare!


In English, we use the prepositionfor‘ to talk about an amount of time, days or space while ‘since‘ refers to a point of time. 

‘During’ is a preposition which is used before a noun (during + noun) to say when something happens.

‘While’ on the other hand, is used to talk about two things that are happening at the same time.
