What is Subject-Verb Agreement (SVA)?
Subject-Verb Agreement is a fundamental rule of grammar which states that the subject of a sentence must agree with its verb in number.
The Core Principle:
- A **singular subject** takes a **singular verb**. (e.g., A verb with an '-s' ending in the present tense)
- A **plural subject** takes a **plural verb**. (e.g., The base form of the verb in the present tense)
Examples of the Core Principle:
- The dog barks.
Explanation: 'dog' is a singular subject, so it takes the singular verb 'barks'.
- The dogs bark.
Explanation: 'dogs' is a plural subject, so it takes the plural verb 'bark'.
