Sentence structures are categorized by clause combinations: Simple (one independent clause), Compound (two+ independent clauses), Complex (one independent + one+ dependent clause), and Compound-Complex (2+ independent + 1+ dependent clauses). These build from basic patterns like Subject-Verb (SV) to more intricate Subject-Verb-Object-Complement (SVOC) forms, creating varied expression.
1. Simple Sentence
Structure: One independent clause (Subject + Verb).
Example: The dog barked.
2. Compound Sentence
Structure: Two or more independent clauses joined by a coordinating conjunction (FANBOYS: for, and, nor, but, or, yet, so) or semicolon.
Example: The dog barked, and the cat ran away.
3. Complex Sentence
Structure: One independent clause and one or more dependent clauses (starting with subordinating conjunctions like because, although, if).
Example: Because the dog barked, the cat ran away.
4. Compound-Complex Sentence
Structure: Two or more independent clauses and at least one dependent clause.
Example: Because the dog barked, the cat ran away, and the owner woke up.
