I'm not sure how people learn how to write or read without using a dictionary and/or Thesaurus like this. The more I think about it, I'm not sure how language would even develop in the first place if this were true. The way I learned to write was by scouring the related words in the Thesaurus to find the closest word to convey the feeling I had. Isn't every new word learned and invented using a similar process? I'm just imagining the first ancient human inventing a word for "wolf" and another member of the tribe silently thinking to themselves that this overly intellectual showoff is just gatekeeping, but sadly can't express his thoughts without physicaly lashing out.
