Sentence structure refers to the way words are arranged to form a complete sentence that expresses a clear thought. A sentence generally consists of a subject, a predicate, and may include objects, complements, and modifiers. There are four main types of sentence structures: simple, compound, complex, and compound-complex. A simple sentence has one independent clause, while a compound sentence joins two or more independent clauses with conjunctions. A complex sentence includes one independent clause and at least one dependent clause, and a compound-complex sentence combines both. Proper sentence structure ensures clarity, coherence, and grammatical correctness in communication.
