Here is a worksheet on distinguishing empathy from sympathy when using these words in English prose. This is a full-page worksheet with ten modified cloze exercises. But if you want to do something else with this document, it is, like almost everything else on this blog, formatted in Microsoft Word for ease of adaptation to your classroom’s needs. The reading is short, but gives a clear sense of the use of these abstract nouns, including a caveat against confusing emphasize with empathize.
Also, in keep with the policy at Mark’s Text Terminal of giving credit where it is due, let me just mention that the text for this worksheet is drawn from Paul Brians’ excellent book Common Errors in English Usage, which is available at the Washington State University website.
If you find typos in this document, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
