"This is the story not of my particular emotions but rather of Theory. Suffice it to say that the self-parody of the appellation, singular and majuscule as if affixed in Plato’s firmament, appeared to rule out all interpretations competing with that of shenanigan. So, too, did the buffoonery of the language, phraseology bloated past the point of grotesqueness." -- Rebecca Newberger Goldstein, 'Theory, Literature, Hoax,'
Majuscule derives from the Latin majuscula, related to "major."
