The first condition is that of cross-syllable slot matching. Fromkin (1971) and many others have observed this constraint in segmental slips-of-the-tongue and Buckingham and Kertesz (1976) correlated these observations with chi structure of perseverative transpositions in neologistic jargon. Most characterizations of the constituent structure of the syllable initially divide the syllabi into an onset and a core (or rime). The onset position is made up of zero or more consonants, and it stands apart from the rest of the syllable.
