A term originating in logic, and now widely used in syntax, semantics and pragmatics. In its strictest sense, scope is defined syntactically: if an operator O combines with some other expression E, then E is the scope of O. As a general illustration, in English the scope of negation typically extends from the negative word until the end of the clause. Adverbials, interrogative forms and quantifiers are among the expressions which are often analysed in terms of scope. Sentences where there is an ambiguity deriving from alternative scope interpretations are said to exhibit a scope ambiguity.
