Syntactic structure refers to the arrangement of words and phrases to create well-formed sentences in a language. It involves understanding how different parts of speech, such as nouns, verbs, and adjectives, interact to convey meaning. The rules governing this arrangement are known as syntax, which varies across different languages. In linguistics, syntactic structure is crucial for analyzing sentence formation and understanding how meaning is constructed. By studying syntactic structures, researchers can identify patterns and rules that help explain how sentences are formed and interpreted, contributing to our knowledge of language development and communication.
