This thesis provides a detailed description and analysis of the Mankiyali phonology, a hitherto undocumented and endangered language of northern Pakistan. The language is spoken by about 500 people in a remote mountainous area in the Mansehra district of Khyber Pakhtunkhwa Province, Pakistan. The data contained herein is a result of first-hand fieldwork with native Mankiyali speakers between 2019 and 2021. Data collection methods include recordings of naturally occurring discourse (e.g., stories, poems, conversations) and elicitation sessions with native speaker consultants. Topics covered in the thesis include an account of Mankiyali's phonemic inventory, phonotactics, a description of some phonological processes, minimal word constraints, and word stress placement.

This study is the very first detailed description of the (finite) verb morphology in Azamgarhi, a unique Awadhic Indo-Aryan language spoken exclusively by a significant number of Muslims of the Azamgarh region of Uttar Pradesh, India. It is a part of a broader goal of holistic and comprehensive documentation of the Azamgarhi language, filling a gap in the descriptive literature, beginning with a detailed discussion on the social and linguistic background of the language in question and then moving to discuss the morphology of verb stems and their uses. The data presented here is based on analysis of elicited and textual materials from mainly the Southern dialect. Azamgarhi verbal morphology constitutes derivation and inflection.

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.
