In the Salish language Halkomelem, there are numerous functional elements that we identify as clitics. In this study, we seek to improve our understanding of Halkomelem clitics by classifying them according to their syntactic and phonological properties. We look in particular at data from the Island dialect, called Hul'q'umi'num'.First, based on their patterns of syntactic placement, we classify Hul'q'umi'num' clitics into two general types, inner and outer. Inner clitics are more constrained in their placement than outer clitics. When they co-occur, inner clitics are closer to the host than outer clitics are. Second, we examine Hul'q'umi'num' clitics in terms of phonological integration, showing that clitics are less integrated than affixes, and, furthermore, that clitics that follow their hosts are more integrated than those that precede their hosts.Finally, we analyze the prosodic representations of Hul'q'umi'num' clitics within Prosodic Clitic Theory. We propose that clitics receive at least three different parses in Hul'q'umi'num', namely internal enclisis, adjoined proclisis, and free clisis. That is, clitics can be parsed at the right edge of a prosodic word, at the left edge of a recursive prosodic word, or directly by a phonological phrase. While Hul'q'umi'num' clitics exhibit a range of behaviors, those clitics with more constrained syntactic placement are generally more phonologically integrated, and vice-versa.
