The document discusses different types of sentences: simple sentences contain a subject and verb, and may include objects, complements or modifiers. Compound sentences join two simple sentences with a conjunction like "and". Complex sentences contain two clauses joined by conjunctions like "when" or "although". When writing sentences, proper grammar must be followed regarding subject-verb agreement, avoiding fragments, using correct parts of speech and tense. Commas alone cannot join sentences; a conjunction is needed to avoid a comma splice error.
