Finally this morning, here is a worksheet on the Greek word roots op, ops,opt/o, opthalm/o,-opia, and opsy. They mean, variously, eye, visual condition, vision, sight, and inspection. This is a productive set of roots from which grow a diverse vocabulary that includes (on this document), autopsy, biopsy, ophthalmology, and synopsis.
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.
