In linguistics, syntax ( ) is the study of how words and morphemes well-formed combine to form larger units such as phrases and sentences. Central concerns with syntax include word order, grammatical relations, hierarchical sentence structure (constituency), agreement, the nature of crosslinguistic variation, and the relationship between form and meaning (semantics). Diverse approaches, such as generative grammar and functional grammar, offer unique perspectives on syntax, reflecting its complexity and centrality to understanding human language.
