Updates to lessons 22 and 23
I have updated lessons 22 and 23 (Present and Imperfect Middle/Passive). The changes to lesson 22 are very minor—just a few wording changes. The main change to lesson 23, though, is the deletion of the discussion on transitivity. I will introduce that topic in a later lesson with much better examples. This change helps unnecessary complication, tightening the focus on the issue of voice.
I also made a few changes to the course lexicon (cumulative vocabulary list) to improve entries for some of the verbs presented in these lessons.
