If this question is REAL dumb please put it down to being a total Newbie but;
If, "Diana sagittas portat et feras necat" means, "Diana carries arrows & kills wild beasts"
then why is necat not necant ?
The above example is from pg. 18, Lesson IV and is the caption to the page illustration.
I am guessing the answer is; So that the two verbs portat & necat will agree with the subject
