Not to be confused with the homophone intention; or the related concept of intentionality. For the song "Intension" by Tool, see 10,000 Days.

In linguistics, logic, philosophy, and other fields, an intension is any property or quality connoted by a word, phrase or other symbol. In the case of a word, it is often implied by the word's definition. The term may also refer to all such intensions collectively, although the term comprehension is technically more correct for this.
