Categorically means in a way that's so clear that it's impossible to be confused or uncertain. When your sister categorically warns you against snooping in her diary, there's no mistaking what she means.

If you categorically deny knowing anything about who ate the last chocolate chip cookie, you state clearly and directly: "I did not eat that cookie, and I have no idea who did." In fact, anything you do or say categorically is done or said unambiguously and unconditionally. This adverb comes from categorical, "asserting absolutely," and its Greek source kategorikos, "accusatory or affirmative."
