Comment on the following groups of words in terms of types of antonyms: contradictory terms, contrary terms, relative terms.
“true—false’’，“big—small”，“husband-wife”
①Antonyms can be defined as words which are opposite in meaning. They can be classified into three major groups.
②Contradictory terms: They are so opposed to each other that they are mutually exelusive and admit no possibility between them, such as "true-false".
③Contrary terms: Antonyms of this type are best viewed in terms of a scale funnring between two poles or extremes. Antonyms such as "big-small" represent two points at both ends of the pole and can accommodate middle ground belonging neither to one pole nor to the other. We can have medium-sized between the big and the small.
③Relative terms: This type consists of relational opposites such as "husband-wife". Such pairs of words indicate such a reciprocal social relationship that one of them cannot be used without suggesting the other.If is the husband of B, then B is the wife, who marries A.
