PREPOSITIONS
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.
AT
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
IN
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
We work out in the morning
My son studies in the afternoon
Years, centuries or expressions of time

She will come to the city in a few weeks
In places, specifying you are inside

Cities, states, countries and continents

ON
Use the preposition ON with:

Days, dates and expressions like Tuesday morning and Friday evening

** The preposition ON is used with transportation, but when referring to a car or taxi, use the preposition IN:

We also use ON with avenues and streets
I’m on Bush Street
Refering to a farm or an island
I would like to spend my vacation on a island
The horses live on the farm
