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? – user20792 Dec 16 '15 at 10:39

    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. – Jim Reynolds Dec 16 '15 at 11:54

    Both are grammatical, and the meaning of the second is synonymous with that of the first. – Tᴚoɯɐuo Dec 16 '15 at 12:03

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? – Nathan Tuggy Dec 18 '15 at 23:36
