EXTRA CREDIT: Importance of Subject-Verb Agreement
Subject-verb agreement is essential in writing because it ensures clarity and coherence in communication. When the subject of a sentence matches the verb in number (singular or plural), it helps the reader understand the action being described accurately. For example, the correct sentence “The dog barks loudly” clearly indicates that one dog is performing the action of barking. In contrast, the incorrect sentence “The dog bark loudly” fails to match the singular subject with the plural form of the verb, leading to confusion and grammatical error. This attention to detail in subject-verb agreement enhances the professionalism and readability of writing.
