Grammar: Prepositions of Time & Place

The three most common prepositions of time and place are at, on, and in . The key is to remember they move from specific to general.

AT

(Specific / A Point) Time: Used for precise times. *at 8 o'clock, at midnight, at lunchtime.* Place: Used for specific addresses and points. *at 25 Maple Street, at the bus stop, at home.*

ON

(More General / A Surface or Line) Time: Used for specific days and dates. *on Monday, on my birthday, on Christmas Day.* Place: Used for surfaces, streets, and lines. *on the table, on the floor, on Oxford Street.*

IN

(Most General / An Enclosed Space) Time: Used for non-specific times, months, years, seasons. *in the morning, in August, in 1990.* Place: Used for enclosed spaces and larger geographical areas. *in the box, in the car, in London.*
