Explanation:
Antonyms are words that have opposite or opposite meanings to each other. They must belong (like synonyms) to the same grammatical category.
There are three classes of antonyms:
Gradual: The two words gradually oppose; There are other words that mean the same to a different degree. Examples: black and white (there is gray), cold and hot (there is mild, icy, warm ...).
Complementary: The meaning of one eliminates that of the other, incompatible with each other. That is, the affirmation of one implies the denial of the other. For example: If something is legal, it cannot be illegal.
Reciprocals: Designate a relationship from the opposite point of view, you can not give one without the other. Example: buy and sell (for someone to sell something else you have to buy it; if one does not buy, the other does not sell, but you cannot buy something if someone does not sell it).
