Louis A. Flemming, Putnam's Word Book
“ In many instances, however, a list of antonyms is unnecessary. For example, no antonyms of good are found after the synonyms of that word because one thinks of bad instantly when considering the opposite of good; and under bad numerous synonyms, which are also the antonyms of good, are found.It is not an infrequent occurrence for a word to be required that is neither a synonym nor an antonym of a familiar term but merely associated with it in meaning and usage. Such a word cannot when unknown or momentarily forgotten be easily found in a dictionary. ”
