Compound sentences in Kazakh grammar are comprised of two or more independent clauses joined together using coordinating conjunctions, punctuation, or both. Each of these clauses could exist as a standalone sentence, as they all have a subject and a verb. There are various coordinating conjunctions used to join the clauses together, such as және (and), немесе (or), себебі (because), дегенмен (but), etc. Understanding compound sentences is crucial for mastering Kazakh grammar and enhancing language fluency.
