> categorical ≠ silly

In the sentence "See, I can do silly categorical statements too," the adjectives "silly" and "categorical" both modify the noun "statements" and are not themselves related to one another. That's why OP used both of them. If the two words were synonymous, only one would be required.

It's fun nitpicking nitpicks.

i see your careful edit. (i ran out of time myself.) they're called parts of speech. your comment makes much more sense now. welcome.
