The present paper aims at complementing Yeh's (2000a-b, 2003) earlier studies on reduplication in Saisiyat by (i) providing a reassessment of her analyses, (ii) making data available in a more exhaustive manner and (iii) reporting new patterns and meanings. Three patterns of reduplication are examined, Ca-reduplication, partial reduplication-which further includes the following subpatterns: CV-, CVC-, CVV- and -CV-reduplication with overlaps in their semantic functions-and full reduplication. Other issues are also touched on, in particular, the reduplication of certain affixes, and the occurrence of doublet forms. Residual problems regarding the absence of criterion to account for the mapping between a prosodic copying unit and the semantic meaning associated with it are also discussed.
