Prepositions

Dependent Prepositions

Words that require a fixed preposition.

Explanation

Many words need a specific preposition that carries no independent meaning: interested in, good at, depend on, rely on, respect for, increase in. Note agree with a person but agree to a plan, and discuss takes no preposition.

Examples

She is good at explaining difficult ideas.
The result depends on the sample size.
He apologised for arriving late.

Common mistakes

I am interested about history.
I am interested in history.
Interested always takes in.
It depends of the weather.
It depends on the weather.
Depend takes on.
We discussed about the plan.
We discussed the plan.
Discuss takes no preposition.
