This article investigates the structural, semantic, and morphological features of compound proper nouns in English and Uzbek from a cross-linguistic perspective. Proper nouns occupy an important place in linguistic systems because they identify unique entities such as people, geographical locations, organizations, historical events, and institutions. Compound proper nouns are especially significant because they reflect cultural identity, historical traditions, and linguistic development. The study analyzes similarities and differences between English and Uzbek compound proper nouns through comparative linguistic methods. The research relies on theoretical approaches proposed by scholars in morphology, onomastics, syntax, and comparative linguistics. Findings indicate that English compound proper nouns demonstrate greater orthographic flexibility, while Uzbek compound proper nouns preserve stronger agglutinative and syntactic characteristics. The article contributes to comparative linguistics and onomastic studies by highlighting language-specific patterns and universal tendencies in naming structures.
