Do you have any knowledge at photography?

Is this sentence correct? I don't think so, the at doesn't sound right, but my friend says some grammar checker tells that its correct?

  • One of the easiest things to do is to check dictionaries for usage: ODO | Cambridge | MW to see what their examples use in similar sentences. They are all knowledge of. Also, it would be useful to know what "some grammar checker" actually was. – Andrew Leach Jul 5 '14 at 15:59


I think this is better:

"Do you have any knowledge of photography?"

or this variation feels more natural to me:

"Do you know anything about photography?"

  • Exactly..that's what I was thinking. But do you know why that grammar checker didn't catch it? – Sawarnik Jul 5 '14 at 12:56

    @Sawarnik: Software "grammar checkers" are largely a waste of time. This particular preposition usage doesn't meaningfully adhere to any "rules" anyway - it's just established idiomatic preference that native speakers tend to use of, concerning, about, regarding, in constructions involving have knowledge [preposition] [subject]. Things would change if we replaced knowledge with experience, information, but this goes way beyond what dumb software could be expected to handle. – FumbleFingers Jul 5 '14 at 13:03
  • Well, "knowledge at" can work in some contexts: "His general knowledge at times seemed limitless". – Bedfordian Jul 5 '14 at 13:08
  • @FumbleFingers Yup, thanks :) I knew I was right :) – Sawarnik Jul 5 '14 at 14:22
  • As to why the dumb machine told you it was OK: maybe - just guessing - there's a script there telling the machine that if there's a question about a field of expertise (photography, physics, etc.), it's got to be a question concerning "being good AT sth". Or your friend's BSing you :) – jules Jul 5 '14 at 15:55
