- Compound-Complex Sentence: Consists of at least two independent clauses and one dependent clause (e.g., "She walks her dog, and he runs when it is sunny").
Word Order:
- Typical order: Subject + Verb + Object (SVO).
- This order can change in questions and certain sentence structures (e.g., "Is she walking?").

Common Grammatical Errors

Subject-Verb Agreement: Subjects and verbs must agree in number (e.g., "She walks" vs. "They walk").
Incorrect Tense Usage: Avoid switching tenses within a sentence or paragraph unnecessarily; maintain consistency.
Sentence Fragments: Ensure sentences have a main clause with a subject and verb to avoid incomplete statements (e.g., "Because she was tired" is a fragment).
Run-on Sentences: Use proper punctuation to separate independent clauses; avoid joining them without a conjunction or proper punctuation (e.g., "She walks her dog. She also runs" vs. "She walks her dog, she also runs").
Misplaced Modifiers: Place modifiers next to the words they describe to avoid ambiguity or confusion (e.g., "She gave the dog a bone that was hungry" should be "She gave a bone to the hungry dog").
