In English, there are several prepositions. In this section we will see the use of three of them: in, on and at. They can cause difficulty in their use because in general these three prepositions can have the same meaning.



We use AT with clock times:

My class starts at 8 o’clock


Special Dates:

I will see you at Christmas

She wasn’t there at Easter

** When there is the word “DAY” after the commemorative date, we do not use AT. Use ON:

My brother will arrive on Christmas Day


We also use At with the words: noon, night, midnight and dawn.

She arrived at dawn

See you at night


Complete Addresses:

Joshua lives at 74 Lincon Street



In places, but without specifying you are inside.

I’m at the movie theater waiting for you




Use the preposition IN with:


Months or Seasons of the year

My birthday is in April 

It’s very cold in winter 


With morning, afternoon and evening
