In many cases there are large parallel sets of tentative phonemes, in which the corresponding members of phonemes from each set differ in what are called features of syllabification. Such are the differences between the second elements of 'analysis', 'a name', and 'an aim', or the second elements of 'attack', 'a tower' and 'at our'. Here, instead of speaking of three phonemically different /n/ elements, or three /t/ elements, and instead of speaking of one set of elements /n,t/ etc. plus various syllabification rules, we can speak of one set of elements plus one juncture /-/ which may occur before or after the element or not at all: 'analysis' /ænæ lisis/, 'a name' /æ-neym/, 'an aim' /æn-eym/.
