I usually use the plural form after "some."


I bought some books about France

But I would also say some source states that France is best toured in fall. Is there a specific grammar rule? May I say that in the second sentence I am really thinking at a very specific source, so singular is needed?

Some has slightly different meanings depending on whether it is used with a singular or plural noun. When you say, "I bought some books," you mean that you bought multiple books, but not how many were purchased.

With a singular noun, some is used to talk of something whose existence is known, but whose nature or identity is not.

She is in some kind of trouble.
There must be some mistake.

    +1. "I bought some books" ==> "I bought multiple books". "I bought some book" ==> "(informal colloquial) I bought a random book"

    I'd add that unless you're using it in Matt's informal colloquial sense, or it's a special case like "some kind" or "some mistake", some + singular noun is incorrect. Specifically, the OP's "some source states that..." doesn't work.

    You could say "one source states that..." or "a source states that...", or even "one of my sources states that...". However, "some source states that..." is definitely wrong. You could also say "some sources state that..."
