The chapter identifies four prominent methods of expressing restriction. All can narrow a relation, but they differ in whether negation is explicit and how the assertion is foregrounded.
1. Coordination (العطف): affirming an attribute while excluding another.
2. Negation and exception (النفي والاستثناء): “mā Zaydun illā shāʿir.”
3. Innamā (إنما): “innamā Zaydun kātib,” a common restricting construction.
4. Preposing (التقديم): moving a constituent forward to mark rhetorical focus or restriction.
Recognizing the method is only the beginning: identify the restricted element (المقصور), the element restricted to (المقصور عليه), and the alternative being excluded.
