Explanation:

Reference and sense

We are looking at relationship between the linguistic expression and the entity in the real world to which it refers. In differentiating reference from sense, sense is interpreted as its relations to other expressions in the language technique. That is, there are words that have a sense, but no referents in the real world. Other words may differ in sense, but not necessarily in reference, and vice versa.

The class of entities to which an

the expression can be used is usually named as extension. Therefore, the referent of a word is always a component of the class of entities that comprises those extension. And on the other side of it, the word's intension, can be interpreted as the set of semantic properties.
