This self-paced workbook homes in on (not hones in on) the word-pairs that even professional writers and editors sometimes find confusing. It explains the differences between the two words, gives tips for using them correctly, and provides some good memory hooks to keep them locked in place. Some of the pairs are imply-infer, who-whom, compliment-complement, and affect-effect.
