In other words, a syllable is not allowed to begin with a consonant cluster that is not found at the beginning of some word, or end with a cluster that is not found at the end of some word (Goslin and Frauenfelder, 2001).
a word like admit [dmÁt] must be syllabified [d-mÁt] because [dm] never appears word-initially or word-finally in English.
