I’ve uploaded a slightly revised version of Lesson 19: Semantic Roles and Voice: the Aorist Passive.
The changes are designed to make it clear that what has traditionally been called the Aorist Passive is a set of forms that, while they often suggest a passive interpretation, are not exclusively (or even primarily) passive.
The middle voice will be introduced later, and at that point I will have more to say about Greek voice, and I’ll introduce the notion of transitivity. My goals for this lesson are simply to introduce the notion of the semantic roles AGENT and PATIENT—establishing their independence from specific morphological Case forms—and to introduce the forms traditionally called aorist passive.
I would love to hear from readers about how well you think I have accomplished these goals and about how clearly (or unclearly) I have handled the issue of insuring that students do not equate these forms exclusively with passive voice interpretations.
