Prepositions after adjectives

Disinterested in, with, at, to or on?

The usual pattern is disinterested in something, meaning not interested. Other prepositions are usually separate context phrases rather than fixed combinations.

Quick answer

Which preposition goes with disinterested?

The standard combination is disinterested in something. It means lacking interest or enthusiasm. Prepositions such as with, at, to, and on are not normally selected by disinterested itself, though they may appear in a sentence for other reasons.

Choose the pattern by meaning

These forms are not interchangeable. Choose the construction by meaning, not by which preposition appears most often.

1
disinterested in + noun

Showing lack of interest in something

Use disinterested in before a thing, activity, or topic.

The audience was disinterested in the presentation.
I'm disinterested in celebrity gossip.
2
disinterested in + gerund

Showing no desire to do something

Use a gerund after in to describe an activity.

3
disinterested with + noun

Using with as a separate adjunct

With is not the normal complement after disinterested. It may introduce a separate phrase about company or circumstance.

4
disinterested at + event

Using at for location or occasion

At can describe where someone is disinterested, but the adjective itself still usually takes in for the topic.

She looked disinterested at the meeting.
