winter

denotation: the season between autumn and spring.  外延

“intension” indicates the internal content of a term or concept that  constitute its formal definition; 

“extension” indicates its range of applicability by naming the particular objects that it denotes.

For example, the intension of a car is the all-inclusive concept of a car, including, for example, mile-long cars made of chocolate that may not actually exist.

But the extension of a car is all actual instances of cars (past, present, and future), which will amount to millions or billions of cars, but probably does not include any mile-long cars made of chocolate.
