Charles Gerras. The synonym finder. , Rodale Press, 1978.

The Synonym Finder follows dictionary format. Entries are arranged alphabetically, with all appropriate parts of speech included under a single headword. Homographs — words spelled identically but of different origins — are entered separately with an identifying superior number. Word listings have been organized numerically according to definition and major semantic groups; further discriminations are shown within these groups by separating subgroups by semicolons.
