Is there an "e" in judgment? When do you imply rather than infer? The only resource that answers both these questions is The McGraw-Hill Dictionary of Misspelled and Easily Confused Words. It's the only book that includes commonly misspelled words and a comprehensive usage guide in one handy volume. Featured are 7,000 of the most commonly misspelled words with their incorrect and correct spellings and a guide to demystifying homophones (cite vs. site), grammatically troublesome words (can vs. may), and subtly different words (imply vs. infer).
