Any kind of + plural word [duplicate]

Nouns related to "any" are correctly singular, when there is the possibility that only one thing might be involved.

  • "Any person can do this"
  • "He looked for any kind of evidence"
  • "Any solution is better than none"
  • "This works for any kind of drawing"

Using "all" requires plurals:

  • "All people can do this"
  • "This works for all kinds of drawing"

The associated noun for words like "kind" should always be singular (though it's not a rule that is widely followed)
