What is "lexical functional grammar"?

Lexical functional grammar (LFG) is a framework in linguistics that focuses on the relationship between syntax and semantics, emphasizing the role of lexical items in the structure of sentences. LFG posits that sentences are composed of various layers of structure, including syntactic structure, how words combine, and functional structure, the roles that different parts of the sentence play. This approach highlights the importance of grammatical relations, such as subject and object, and how they interact with the meanings of the words involved. LFG allows for a flexible analysis of different languages, making it useful for understanding the complexities of language and the connections between form and meaning.
