I want to know, if there is any, the difference between the following sentences:


  • 1
    Really, there's no difference. As a native English speaker, #2 sounds more casual and #1 a bit more formal, but ultimately they mean the same thing.

The biggest difference is that on is a gerund (gathering evidence) and the other is a noun (evidence-gathering). If you were making a list and wanted the language to be parallel, one list of responsibilities could be:

  • Gathering evidence
  • Interviewing witnesses
  • Photographing the scene

Stated differently, the list would read:

  • Evidence gathering
  • Witnesses interviews
  • Scene photographs

The meaning conveyed did not change despite the shift in language.
