A word found only in dusty old tomes, lost quasi-permanently to the sands of time by the year 20X6. Aside from the old news footage and blog posts reviewed in history lessons, for which students begrudgingly consult their handhelds, it is glossed over with disinterest. In the twenty-Xth century there is no need for a three-syllable word where one will do. "Naturally" has been left to rot with parachute pants, disco and the term "information superhighway".
Cool people say "natch", anyway.
