A complete change of shape or form, so complete and so strange that it seems like magic. It is the noun of 'transmogrify'. The heart of this word is its tone: it is playful. English already has 'transformation' for a serious change, so when a writer reaches for 'transmogrification' instead, they are almost always smiling — the change was odd, sudden, comic, or slightly absurd. It fits a prince turning into a frog, a shy student turning into a rock star, a plain office being transmogrified into a jungle of plants, a wholesome book transmogrified into a violent film. It also works well when the speaker is a little sceptical, hinting the change was ridiculous rather than admirable. Nobody knows where the word really came from — it appeared in English in the 1600s and looks made-up, which is part of the fun; even dictionaries say the origin is unknown. It is a long, showy word, and using it draws attention to itself, which is exactly why it is used. Many younger readers first met it in the comic strip Calvin and Hobbes, where Calvin builds a cardboard box called the Transmogrifier. Uncountable most of the time, but you can say 'a transmogrification' for one particular change.
