There’s some I6 code to do something like that in this post. You could insert that code and then say “type of noun” where you currently have “kind of noun.” It prints with an initial capital for some reason but you could easily write some code to get around that (just define a substitution that prints the type of the noun in lower case). This works in version 6L02 of Inform 7; I haven’t checked in 6L38.
