In the previous quizzes we learnt what antonyms are and also about the different types of antonyms, such as graded and complementary. We now come to one more type of antonym known as Relational Antonyms.
Relational antonyms are words such as LOST/FOUND and BUY/SELL. For such words a relationship is there provided both exist. For instance, for somebody to buy, someone else must sell. If something is lost only then can that thing can be found. Other examples would be floor/ceiling; up/down and win/lose.
Not all similar pairs of words are relational antonyms. You could get confused between husband/wife and son/daughter. While these two pairs are similar they are different types of antonyms. For the husband to exist the wife must be there and hence they are relational antonyms. But for a daughter to exist a son need not exist and vice versa. The son/daughter pair is categorised under complementary antonyms.
