I want to say

"They belong to different classes."

Is it right to say

"They differ in class." ?

    It is unclear what you are asking. Your first sentence could mean many things, because class has different meanings. Could you add more context?

    It's clear that class is being used to mean category, or some kind of category. I don't think it matters which (e.g., grade in school, socio-economic level, or "type" in general), in order to be able to answer the question. It should be re-opened so that it can be answered.

    Both are grammatical, and the meaning of the second is synonymous with that of the first.

The second sentence is perfectly fine for some meanings of class but not others. The first sentence uses class to refer to a grouping, as a count noun.

However, the second sentence only works if class is also an intrinsic quality (social standing, technical complexity, biological taxonomy, etc).

  • This looks fairly reasonable. Would you mind editing the question somewhat to clear up the understanding of it that led you to be able to answer it? Dec 18, 2015 at 23:36
