Intensional/extensional A rather large and especially useful portion of our active vocabularies is taken up by general terms, words or phrases that stand for whole groups of individual things sharing a common attribute. But there are two distinct ways of thinking about the meaning of any such term. The extensional of a general term is just the collection of individual things to which it is correctly applied. Thus, the extension of the word "chair" includes every chair that is (or ever has been or ever will be) in the world. The intension of a general term, on the other hand, is the set of features which are shared by everything to which it applies. Thus, the intensional of the word "chair" is (something like) "a piece of furniture designed to be sat upon by one person at a time." Fig.
