capitulum IV: pēnsum A

Work on the new endings: the vocative (-us --> -e; -ius --> ī); and the imperative (-at --> -ā; -et --> -ē; -it --> -e; -it --> ī).
The 3rd and 4th conjugations have to be learned as they come. For example, venit is 4th conjugation, and so 'Come!' is 'Venī!'; discēdit is 3rd conjugation, and so 'Leave!' is 'Discēde!'. See the vocabulary lists and memorize what verb family each verb belongs to.
Bona fortūna!
