The set of rules for proper sentence structure is called?

• A. Grammar
• B. Syntax
• C. Phonology
• D. Morphology

Answer: (A)

The main idea here is understanding what term names the rules for forming sentences in English. Grammar is the umbrella for the system of language rules, including how sentences are constructed, how words change form, and how punctuation fits in. While syntax specifically tackles word order in sentences, grammar covers that plus other aspects of sentence structure and language use. Phonology deals with sounds, and morphology concerns word formation. Because the phrase “set of rules for proper sentence structure” points to the overall framework governing how sentences are built, grammar is the best match.
