Montague Grammar is a formal approach to natural language semantics developed by the American logician Richard Montague in the 1970s. It combines elements of formal logic and linguistics to analyze the meaning of sentences in a precise way, using mathematical structures to represent linguistic expressions. The framework emphasizes the importance of syntax and semantics working together, allowing for a systematic interpretation of language. By treating sentences as mathematical objects, Montague Grammar provides tools for understanding how meaning is constructed and how different components of language interact, influencing fields like computational linguistics and philosophy of language.
