Some constraints on medial consonant clusters

It can be argued that syllable shape is a function of the morpheme structure constraints in a given language—and that, in segments more than one syllable long, the composition of medial clusters is a reflection of those constraints as they apply to initial and final groups. Further, given a convention for syllable bracketing, it is possible to show a further characteristic of medial clusters: namely, that they ideally overlap, i.e. have simultaneous membership of both the preceding and following syllable segment. Examples will be chosen from the diachronic phonology of English to illustrate the last two characteristics of syllables and to further support the claim that the syllable is a phonological prime.
