Here is a worksheet on differentiating and using the adjectives later and latter. This full-page worksheet (adapted, as always with documents under the header above, from Paul Brians’ book Common Errors in English Usage, to which he generously allows open, free-of-charge access at his Washington State University web page) presents a four-sentence reading from Professor Brians’ book followed by ten modified cloze exercises.
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.
