Full Idea
In 'De Interpretatione' Aristotle laid out an enduring theory of reference and meaning, in which we understand a word or any other sign by associating that word with a concept. This concept determines what the word refers to.
Gist of Idea
For Aristotle meaning and reference are linked to concepts
