摘要：Lasi is said to be one of the dialects of Sindhi which is spoken in Lasbela and some districts of Sindh (Azam, 2019; Mustafa, G. & Ali, Z., 2021; Amin, M. & Ali, Z., 2021). The research aims to describe and analyse the use of postpositions in Lasi and Sindhi. The study compares postpositions in Lasi and Sindhi in terms of place and position. This research is a qualitative, and it uses descriptive and analytical research designs. The data have been collected through informal conversation (unstructured interviews) with native speakers of Lasi which have been later reproduced by the Sindhi speakers so that we can have comparison of postpositions between the two languages. Chomsky’s (1988) principles and parameters have been used as a theoretical/analytical framework. The research has shown differences between the two languages; Sindhi and Lasi. It has been found that Lasi and Sindhi differ in the use of postpositions. Sindhi uses a separate word in the postpositional phrase to show the postposition while Lasi uses postpositional suffixes with the noun in the postpositional phrase to show the postposition. The prominent Lasi postpositional morphemes/suffixes are ‘m, k, t, la’. The most interesting finding is that Lasi uses just a phoneme (a consonant) to show a complete morpheme (a word: postposition). However, the two languages have been found similar in the placement of postpositions; both use postpositions after the nouns, because Lasi and Sindhi are head-final languages unlike English.
