Complementaries display a type of oppositeness of meaning, illustrated by pairs such as single/married and husband/wife. Single is said to be the complementary of married and vice versa. In such a relationship, the assertion of one of the items implies the denial of the other (i.e., the entity cannot be both at once). In addition, the relation of ‘complementarity’ is characterised by the lack of any gradability between the items.
