A preposition is a word or group of words used before a noun, pronoun or noun phrase to show direction, time, place, location or spatial relationships, or to introduce an object. Some examples of prepositions are words like “in,” “at,” “on,” “of,” and “to.”

Prepositions in English are highly idiomatic. Although there are some rules for usage, much preposition usage is dictated by fixed expressions. In these cases, it is best to memorize the phrase instead of the individual preposition.

Prepositions of Direction

To refer to a direction, use the prepositions “to,” “in,” “into,” “on,” and “onto.”

    • She drove to the store.
    • Don’t ring the doorbell. Come right in(to) the house.
    • Drive on(to) the grass and park the car there.

Prepositions of Time

To refer to one point in time, use the prepositions “in,” “at,” and “on.”

Use “in” with parts of the day (not specific times), months, years, and seasons.

    • He reads in the evening.
    • The weather is cold in December.
    • She was born in 1996.
    • We rake leaves in the fall.

Use “at” with the time of day. Also use “at” with noon, night, and midnight.

    • I go to work at 8:00.
    • He eats lunch at noon.
    • She often goes for a walk at night.
    • They go to bed at midnight.

Use “on” with days.

To refer to extended time, use the prepositions “since,” “for,” “by,” “during,” “from…to,” “from…until,” “with,” and “within.”

    • He will be in Kolkata for 3 weeks. (He will spend 3 weeks in Kolkata.)

Prepositions of Place

To refer to a place, use the prepositions “in” (the point itself), “at” (the general vicinity), “on” (the surface), and “inside” (something contained).

    • They will meet in the lunchroom.
    • She was waiting at the corner.
    • He left his phone on the bed.
    • Place the pen inside the drawer.

To refer to an object higher than a point, use the prepositions “over” and “above.” To refer to an object lower than a point, use the prepositions “below,” “beneath,” “under,” and “underneath.”

    • The park is near her house.
    • Park your bike next to the garage.

Prepositions Following Verbs and Adjectives

Some verbs and adjectives are followed by a certain preposition. Sometimes verbs and adjectives can be followed by different prepositions, giving the phrase different meanings. Memorizing these phrases instead of just the preposition alone is the most helpful.
