Pronunciation is not traditionally considered a part of grammar. Grammar refers to the set of rules that govern the structure of sentences, including syntax (how words are arranged) and morphology (the form of words). It deals primarily with how words interact with one another to create meaning.
Pronunciation, on the other hand, focuses on the sounds of speech—the way words are correctly articulated and heard. While proper pronunciation is crucial for effective communication, it falls under the category of phonetics and phonology, not grammar.
That said, the two elements are interconnected in the language learning process. A solid understanding of grammar can help learners pronounce words correctly, and good pronunciation can aid in understanding syntactic structures in spoken language. However, they are distinct aspects of language study.
