Prepositions after verbs

Disagree with, on, about or in?

Disagree commonly combines with with, on, and about. Disagree in is limited and usually refers to a particular quality or area.

Quick answer

Choosing the right preposition after disagree

Use disagree with for a person, opinion, or statement. Use disagree on or disagree about for a topic or issue. Disagree in is less common and usually refers to a specific aspect: They disagree in style.

I disagree with your conclusion.

We disagree about how to proceed.

With usually follows a person, idea, or statement, not a discussion topic.

Using in for ordinary debates

Disagree in is limited to qualities or aspects.
