Does grammatical structure refer to how words sound in a sentence?

No, grammatical structure refers to how words are arranged in a sentence to convey meaning, not how they sound.

Here's why:

* Sound: The way words are pronounced is part of phonology.

* Structure: Grammatical structure focuses on the order of words, parts of speech, and their relationships. This includes things like:

* Subject-verb agreement: "The cat sits" vs. "The cats sit".

* Word order: "The dog chased the ball" vs. "The ball chased the dog."

* Parts of speech: "The tall man walked quickly."

Example:

"The cat sat on the mat."

* Structure: Subject (cat) + verb (sat) + prepositional phrase (on the mat)

* Sound: The pronunciation of each word is not relevant to the grammatical structure.
