Usage: philosophy, logic, linguistics; contrasts with extensionality
2. In logic and semantics, the characteristic of expressions whose truth value or reference depends on the meanings or intentions involved rather than on the actual objects denoted.
Usage: formal logic, semantics

Examples

• The intensionality of the word 'unicorn' lies in its meaning, even though no unicorns actually exist.
• Philosophers debate whether belief reports exhibit intensionality or extensionality.
• The intensionality of modal contexts makes them difficult to analyze in formal logic.
• Unlike extensional definitions, intensionality focuses on the properties that define a concept.
• The intensionality of language allows us to discuss fictional and abstract entities meaningfully.
