This paper investigates the grammatical roles of subject clauses and predicative clauses in English and Karakalpak languages that differ significantly in their typological structure. The main issue addressed is the lack of detailed contrastive studies on these types of subordinate clauses, even though they play a crucial part in building complex sentences and organizing information.

The importance of the topic lies in its practical value for contrastive linguistics, translation, foreign language teaching, and a better understanding of the syntactic features of Turkic languages.

Using a contrastive-descriptive method grounded in functional-semantic principles, the study compares how these clauses are structured, how they are linked to the main clause, their typical position, and the semantic weight they carry in both languages. The analysis draws on well-established English grammars as well as key syntactic sources on the Karakalpak language, with special attention to correlative constructions.

The findings show clear typological differences: English mainly uses finite clauses introduced by explicit complementizers and often applies extraposition, whereas Karakalpak tends to rely on analytic-correlative structures involving interrogative and demonstrative pronouns. These structural differences considerably influence clause positioning and the way information is conveyed. The study also offers practical suggestions for improving translation techniques and teaching English as a foreign language to Karakalpak-speaking students.
