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

The [[meaning]] of a [[word]] can be [[thought]] of as the bond between the [[idea]] or [[thing]] the [[word]] refers to and the word itself. Swiss linguist [http://en.wikipedia.org/wiki/Ferdinand_de_Saussure Ferdinand de Saussure] [[contrasts]] three [[concepts]]:

Intension is [[analogous]] to the signified, extension to the referent. The intension thus links the signifier to the sign's extension. Without intension of some sort, [[words]] can have no [[meaning]].

In [[philosophical]] [[arguments]] about [http://en.wikipedia.org/wiki/Dualism dualism] versus [http://en.wikipedia.org/wiki/Monism monism], it is noted that [[thoughts]] have intensionality and [[physical]] objects do not (S.E. Palmer, 1999)

Intension and intensionality (the state of having intension) should not be confused with [[intention]] and intentionality, which are pronounced the same and occasionally arise in the same [[philosophical]] [[context]]. Where this happens, the [[letter]] s or t is sometimes ''italicized'' to emphasize the [[distinction]].
