of the Perfect. We learned in Sec. 186 that any
perfect is inflected by adding the endings of the perfect to the
perfect stem. The inflection in the four regular conjugations is then
as follows:

CONJ. I ama:vi: _I have loved_, _I loved_ or _did love_
CONJ. II monui: _I have advised_, _I advised_ or _did advise_
CONJ. III re:xi: _I have ruled_, _I ruled_ or _did rule_
ce:pi: _I have taken_, _I took_ or _did take_
CONJ. IV audi:vi: _I have heard_, _I heard_ or _did hear_

1. The first person of the perfect is always given as the third of the
principal parts. From this we get the perfect stem. _This shows the
absolute necessity of learning the principal parts thoroughly._

2. Nearly all perfects of the first conjugation are formed by adding
-vi: to the present stem. Like /amavi\ inflect /paravi\, /vocavi\,
/curavi\, /laudavi\.

3. Note carefully the changing accent in the perfect. Drill on it.
