The three papers contained in this document cover particular issues in diverse languages. The first concerns the distribution and function of postpositions in Awutu, an African language; the main function of such morphemes is marking case. The second paper discusses the unusual phonology system of Wichita; this American Indian language is characterized by a three-vowel system that has only height contrasts and a phonemic consonant system with neither labials nor nasals. The final paper discusses the Japanese case markers "wa" and "ga" within a framework similar to Fillmore's case grammar; the author argues on both semantic and syntactic grounds that wa- and ga-noun phrases are transformationally derived from conjoined sentences.
