Error Correction (Chapter 13): Identifying grammatical errors (subject-verb agreement, tense consistency, pronoun misuse). Common errors: Misplaced modifiers, dangling participles, comma splices, run-on sentences. Correction techniques: Read aloud, check each sentence structure, compare similar constructions. For accountants, error correction prevents communication misunderstandings in reports. Exam tip: Identify error type; understand correction principle; apply consistently.
