On affricates The representation of affricates (and other ``two-phase'' segments) is far from being undisputed in phonological theory. Some researchers have even questioned whether affricates are monosegmental or rather consonant clusters. Though at present there seems to be consensus on the monosegmental analysis, how this segment should be thought of is a debated issue. This paper collects evidence for and against various views on affricates and it will offer a solution in a unary-element framework which dispenses with any meaningful distinction between contour and non-contour segments. As this paper is planned to be the outset of a larger scale work on segmental representations, I will leave a large number of problems open for further research.
