When we read, we are, we must be, repeating the words to ourselves unconsciously; for how else should we discover, as we have all discovered in our time, that we have been mispronouncing a word which, in fact, we have never spoken? I refer to such words as ‘misled’, which I, and millions of others when young, supposed to be ‘mizzled’.

— A.A. Milne

This quote brings to mind all the Harry Potter fans who pronounced Hermione as “Hermy-own” in the years before the films were released.
