Putnam's Word Puzzle app for iPhone and iPad

Enjoy English Synonyms, Antonyms, and Associated.
"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. In this volume collections of such words are found after the general terms with which they are associated. This feature of the book will be of service as a memory-help when a word cannot be recalled and also, which is perhaps of greater importance, by enabling writers and students to learn of words objectively or through their associations."
So much beautiful work they made and this is really helpful to whom; blogger, writer, reporter, foreign language learners.
