Here's why:
* Syntax is the set of rules that govern how words are combined into phrases and sentences. It deals with the structure and order of words in a sentence, ensuring that the meaning is clear and understood.
* Grammar is a broader concept that encompasses syntax as well as morphology (the structure of words), phonology (the sound system of a language), and semantics (meaning).
* Structure refers to the arrangement of elements within a sentence, phrase, or paragraph.
Therefore, syntax is the specific term that captures the unique combination of words, grammar, and structure that makes a language understandable.
