Which system governs the order and combination of words to form sentences and the relationships among the elements within a sentence?

• A. Morphology
• B. Syntax
• C. Semantics
• D. Pragmatics

Answer: (B)

Syntax is the rule system that governs how words are ordered and combined to form sentences and how the elements inside a sentence relate to one another. It determines how subjects, verbs, objects, and modifiers fit together, how phrases are built, and how changes in word order can change or preserve meaning while staying grammatical. This is different from morphology, which studies the internal form of words (like roots and affixes); semantics, which focuses on meaning; and pragmatics, which looks at language use in context and intention. For example, standard English tends to follow a subject-verb-object order, as in “The girl reads a book.” Altering the order in ways that violate syntax—like “Reads the girl a book”—often results in ungrammatical sentences, even if the core idea remains similar. Understanding syntax clarifies how sentences are constructed and why certain structures are allowed or disallowed, which is essential when evaluating language abilities and disorders related to sentence formation and comprehension.
