Lesson 15: Third Declension Consonant Stem Nouns

I have revised lesson 15 to reduce the size of the vocabulary list and clean up the discussion of third declension nouns. I have entered some revisions for lesson 16 as well, but will complete those over the next few days—long distance, from Peru.

What should be in a web-based introductory grammar?
