Prepositions in English

2,710 fill-in-the-gap exercises across 6 forms

Small words that fix a noun in space, in time or in relation to something else. Most of the difficulty is in three of them.

Pick a form to practice

in, on, at — the core of the problem

These three cover most of the trouble, and each has a place meaning and a time meaning.

Place

Time

A rough way to remember it: the periods get shorter as you go in → on → at.

The fixed phrases

Some combinations simply have to be learned, because no rule predicts them:

at night but in the morning; on time (punctual) but in time (early enough); at the weekend in British English and on the weekend in American.

After verbs and adjectives

Many words take one particular preposition and no other:

good at, interested in, afraid of, married to, depend on, listen to, wait for, look for, arrive at

And some take none at all, although learners often add one:

discuss, enter, answer, phone, marry — phone me, not phone to me.

What follows a preposition

Always a noun or an -ing form, never a to-infinitive:

before leaving, instead of waiting, good at cooking

This rule has no exceptions, including when the preposition happens to be to: I look forward to hearing from you.

Mistakes to avoid

Wrong: I arrived to the station. correct: I arrived at the station.

Arrive takes at for a place and in for a town or country, never to.

Wrong: She is good in cooking. correct: She is good at cooking.

The fixed phrase is good at.

Wrong: We discussed about the problem. correct: We discussed the problem.

Discuss takes no preposition at all.
