This dissertation presents in-depth description and analysis the Zophei sound system within the context of the closely-related Maraic languages. Zophei (or Zyphe, ISO 639-3 ZYP), a previously undocumented member of the Maraic branch of Kuki-Chin (or South-Central Tibeto-Burman) spoken in Southern Thantlang Township, Chin State, Burma/Myanmar and by thousands of speakers in Indianapolis, Indiana. Using primary data elicited during three years of fieldwork, the sound systems of Lawngtlang, Tlawngrang, and Nuitah Zophei are investigated in detail. Special attention is paid to the segmental, syllable structure, and tonal inventories. A long history of language contact in the Maraic-speaking world has brought on radical innovations in syllable structure, vowel systems, and tone that have, as of yet, seen little linguistic analysis. Outside of the present research program, no previous linguistic work on Zophei exists. As such, this thesis endeavors to describe and analyze the sound systems of Zophei varieties.
