What term refers to phrase and sentence structure in grammar?

The term that refers to phrase and sentence structure in grammar is "syntax." Syntax involves the arrangement of words and phrases to create well-formed sentences. It encompasses the rules and principles that dictate how words combine to form meaningful utterances, affecting clarity and coherence in communication. Understanding syntax is essential for effective reading and writing, as it enables readers to comprehend the intended meaning behind sentences and allows writers to convey their thoughts clearly.

Syllabication pertains to the division of words into syllables and is more focused on phonetics and pronunciation rather than sentence structure. Lexicon relates to the vocabulary of a language, emphasizing the words and meanings a person can use, but does not address how those words are organized into phrases and sentences. Conjugation involves the variation of the form of a verb to provide information about person, number, tense, mood, or voice, which is specific to verbs and does not encompass the overall phrase and sentence structure.
