during is a preposition used to indicate the occurrence of an action or experience at a specific point in time during a period of time. It can also be used to refer to the entire period of time something occurs.
He worked during the night.
The accident happened during the storm.
She was busy during the week.
They enjoyed their vacation during the summer.
When using ‘during’ as a preposition, it is important to remember that it should not be used in the same way as ‘through’ or ‘throughout’. These two words are used to refer to something that happens throughout a period of time. ‘During’ should be used to refer to a specific time within a period. Another important factor to consider is the presence of a period of time when using ‘during’. The word is followed by a period of time and is therefore not used as a stand-alone preposition.
