Which term refers to the arrangement of words and phrases to create well-formed sentences in a language?

The term that refers to the arrangement of words and phrases to create well-formed sentences in a language is "syntax." Syntax involves the rules and principles that govern sentence structure, including the order of words and how different elements of a sentence fit together to convey meaning. A strong understanding of syntax is essential for constructing coherent sentences and understanding the nuances of language.

The other terms represent different linguistic concepts. Semantics focuses on meaning, particularly the meanings of words and phrases in context. Phonology involves the sound systems of a language, including how sounds are organized and used. Morphology deals with the structure of words and the rules for word formation, including prefixes, suffixes, and root words. Understanding these distinctions enhances one’s grasp of language structure and function, but in this case, it is syntax that specifically addresses sentence formation.
