But Lederer and Dowis are hardly anachronous sticklers. Their section on grammatical myths advocates the judicious splitting of an infinitive, using a preposition "to end a sentence with," and even, sometimes, embracing clichés. "Different from" is almost always right, they say, but "if your ear tells you otherwise, choose different than." Their "rule" concerning comma use states that "If the addition or omission of a comma makes the meaning clearer, add it or remove it even if doing so seems to violate some other rule." How refreshing it is to encounter grammarians who do not live in a vacuum, who know that "connotations are often more important than definitions, and that the true meaning of a word or phrase is the effect it has on readers." --Jane Steinberg
