     Traditional rhetoric was much concerned with the phenomenon of elision, because of the implications for constructing well-formed metrical lines, which would scan well. In rhetorical terminology, an elision in word-initial position was known as aphaeresis or prosiopesis, in word-medial position as syncope, and in word-final position as apocope. A similar classification was made for the opposite of elision, intrusion.

   The students of English were making good progress in getting to grips with the intricacies of informal constructions, peppering their conversations with proverbial idioms and substituting stock phrases like Good morning! and Thank you. with prosiopeses like Morning! and ‛Kyou.

   Now, when the negative begins a sentence, it is on account of that very position more liable than elsewhere to fall out, by the phenomenon for which I venture to coin the term of prosiopesis (the opposite of what has been termed of old aposiopesis): the speaker begins to articulate, or thinks he begins to articulate, but produces no audible sound (either for want of expiration, or because he does not put his vocal chords in the proper position) till one or two syllables after the beginning of what he intended to say.
