2. I. The infinitive form Verbs- 3rd io conjugation
- 3rd io verbs are a variant of the 3rd conjugation

3rd-io’s look EXACTLY like the 4th conjugation except for a few instances:
I. The infinitive form
Capio, capere
II. Commands/Imperative mood
Accipio, accipere = (Imp mood) Accipe, accipite
III. Whenever the 3rd conj. normally would follow an exception to a rule, the 3rd-io often does so too.

3. Cum “When” Conjunctions Yes, it can mean “When” Ok, don’t panic
When you see “Cum” without an ablative immediately following it… then it means “When”
