Nominalization in Uchoi

This paper examines the structure of nominal forms in Uchoi, a Tibeto-Burman language spoken in Tripura. The findings indicate that Uchoi utilizes two primary nominalization processes: derivational and clausal. Derivational nominalization largely forms lexical nouns from verbs—and to a lesser degree from nouns and adjectives—by attaching suffixes such as tʰai, -muŋ, -ma, -kirak, -mari, and -nai. Clausal nominalization derives noun phrases from clauses, typically by adding the suffix -nai to the verb, and occurs across attributive, complement, relative, adverbial, and independent clauses. Fieldwork data for this study was collected from the villages of Ratanpur in the South Tripura district and Depachhera in the Gomati Tripura district during a field visit in September 2025.
