In Belarusian grammar, complex sentences consist of two or more independent clauses that are connected by conjunctions or other linking words. These sentences provide more detailed and richer information, compared to simple sentences. The presence of dependent clauses in complex sentences allows for a clearer expression of relationships between ideas. Mastering complex sentences is an essential part of achieving fluency in the Belarusian language, as it enables learners to convey their thoughts accurately and comfortably in various contexts.
