The extension of the defined concept in example (1) is greater than the extension of the defined concept. Because the products of labor include commodities, but are not entirely commodities. The extension of the defined concept in example (2) is smaller than the extension of the defined concept.

Because the theme of the Peasant Revolutionary War is only a part of history.

Literature is the art that is characterized by literature.

Clause. 3. It should not be a negative form. Such as:

A parallelogram is not a quadrilateral.

This statement does not reveal the connotation of the defined concept, so it is not actually defined.
