The proposed dictionary of antonyms of modern English is a collection of words that are antonyms in the linguistic sense of the word itself, and includes over a thousand antonymic pairs, accompanied by examples of their use in two or more typical antonymic contexts. In some cases, one example is given to illustrate that this antonymic pair has relatively less usefulness. Examples are taken from works by English, American and Australian authors of the 19th-20th centuries, as well as from newspaper and magazine articles. For the convenience of using the dictionary in each article, along with the main antonym pair, the most common antonym words of the same root are given. The dictionary consists of an introduction, the dictionary itself and pointers: an index of root antonyms, an index of affix antonyms, an index of symbols of cited sources.
