Annotation: This thesis investigates the feasible differences between languages, focusing on the diverse structural, grammatical, and phonological variations that exist across different language systems. By conducting a comprehensive cross-linguistic analysis, this study aims to identify and examine the key differences that make languages unique in terms of their linguistic properties. The research delves into morphological, syntactic, phonological, and semantic aspects of languages to unravel the feasible divergences and similarities, shedding light on the intricate patterns that govern linguistic diversity. Through a synthesis of theoretical frameworks, empirical data, and comparative analyses, this thesis seeks to enhance our understanding of the feasible differences between languages and their implications for linguistic typology and language universals. Keywords: Feasible Differences, Cross-Linguistic Analysis, Linguistic Diversity, Morphology, Syntax, Phonology, Semantics, Typological Variation.
