This article provides an in-depth comparative analysis of the morphology of parts of speech in Karakalpak and English, focusing on how each language encodes grammatical meaning through either agglutinative or analytic structures. Although Karakalpak employs a highly productive system of suffixation to express number, case, possession, tense, person, and derivational categories, English relies more heavily on word order, auxiliary verbs, and function words to convey the same meanings. Moreover, the study demonstrates that despite their contrasting typological profiles, both languages maintain parallel communicative functions across nouns, verbs, adjectives, pronouns, adverbs, and relational markers. Furthermore, the analysis highlights systematic differences in inflectional and derivational strategies, while also illustrating functional convergence through numerous bilingual examples. Consequently, the findings reveal not only structural divergence but also linguistic universality, emphasizing that both languages, through different morphological pathways, effectively organize grammatical relations and encode semantic distinctions.
