To cut down on the large number of syllables that you found in the last exercise, some systems are instead based on demisyllables—the first half or the second half of a syllable. (We glue the sounds together in the middle of the vowel.) That is, a demisyllable is either a legal onset followed by a vowel, or a vowel followed by a legal coda. How many demisyllables are there in English (making the same very rough assumptions as the last question)?
