----- 同义词和反义词
Actual references may be multiplied by looking up a synonym or antonym, as well as by consulting cognate words, such as the corresponding noun, verb, or adjective. In some cases common words have been omitted, because they were composed of a root word and a prefix, intensive or privative. Their synonyms and antonyms may be found under the root word. Occasionally within the lists words closely synonymous or antonymic have been grouped within semicolons. The part of speech of a word is designated by an abbrevi ation in such cases as are necessary to save confusion.
