问题：
What are the three kinds of antonyms?
答案：
The three kinds of antonyms are gradable antonyms complementary antonyms and converse antonyms. Gradable antonyms refer to antonyms that differ in terms of degree. For example good and bad. Complementary antonyms are a pair of antonyms complementary to each other; not only the assertion of one means the denial of the other; the denial of one also means the assertion of the other such as male and female. Converse antonyms do not constitute a positive-negative opposition ; they only show the reversal of a relationship between two entities such as husband and wife.
