Which of the following best defines syntax?

The definition of syntax specifically focuses on the arrangement of words and phrases to create well-formed sentences in a language. This concept is crucial for understanding how different structures can convey different meanings and nuances in communication. By analyzing the syntax of a sentence, one can determine its grammatical correctness and clarity, which is essential for effective writing and speaking.

The other options address different aspects of language. The meaning of words pertains to semantics, which deals with understanding the significance of words and how they create meaning in context. The production of speech sounds refers to phonetics and phonology, concerning how sounds are articulated and perceived in language. Understanding social language use relates to pragmatics, which examines how context influences the interpretation of communication in social interactions. Each of these aspects plays a role in language study, but syntax uniquely focuses on the structure and organization necessary for crafting coherent sentences.
