Moving right along on a cool and cloudy Thursday morning in Brooklyn, here is a worksheet on the Greek word roots prot– and proto. It means primitive and first, which helps me understand how we end up, in English, with prototype. Protagonist, however, mystifies me a bit; I suppose because the protagonist is the primary (i.e. first) actor in a situation, the word sensibly springs from prot.
Anyway, this document includes several other words that spring from this productive root, including such scientific words as protoplast, protozoan, proton, and protozoology.
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.
