Affricate consonants consist of two portions: stop closure and frication. Can these portions play different roles in phonetic and phonological processes? In this study, I address the question by probing the behavior of Hungarian affricates under lengthening. I measure the duration changes that affricates undergo in two types of lengthening processes: first, a phonetic process of final lengthening and second, a phonological process of gemination. I show that these two processes alter the internal structure of affricates in very different ways. The results suggest that the difference between phonetic and phonological processes is in fact deeper than a mere difference between gradient and categorical effects.
