Definition & Meaning of "operator grammar"

What is "operator grammar"?

Operator grammar is a linguistic framework that focuses on the role of operators in the structure of sentences, particularly in relation to syntax and semantics. Developed by the linguist Robert Van Valin, this theory emphasizes the idea that certain grammatical elements, known as operators, can modify or control the interpretation of other elements in a sentence. Operators can include elements like tense, mood, and modality, which influence how the action of a verb is understood. Operator grammar analyzes how these elements interact within sentence structures, providing insights into the relationships between syntax and meaning in various languages.
