Reduplicated Adjective Forms in the Yongdeng Dialect of Lanzhou

Reduplication, as one of the morphological construction methods in Modern Chinese, serves as a crucial grammatical device. The Yongdeng dialect, part of the Lanzhou sub-group of the Central Plains Mandarin (Lanyin Mandarin), exhibits a rich array of reduplicated adjective forms. This paper investigates the reduplication of adjectives in the Yongdeng dialect from three perspectives: structural patterns, grammatical meanings, and pragmatic functions. Based on whether the reduplication is complete or partial, six main types are identified and discussed: AA, AABB, ABAB, ABB, AACD, and ABCC. The study analyzes their grammatical roles in expressing degree and state, and explores how these reduplicated forms enhance vividness and imagery in pragmatic usage.
