If you scroll down to the seventh post below this one, you will find a pair of context clues worksheets on the noun autobiography and the adjective autobiographical.
Perhaps this lesson plan on the Greek word root auto–it means self and same–might complement those worksheets, or vice versa. I probably don’t need to tell you how productive this root is in English; it is at the basis of huge number of words used across academic domains.
If you find typos in these documents, 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.
