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.
