Verbs of the 4th Conjugation (-UI)

These verbs belong to the 4th Conjugation: salio, salire, salui, saltum. Note that the PERFECT ends in -UI. Note also that two of the verbs in this episode, salto and insulto, belong to the 1st Conjugation. They are built off of the fourth principal part (salt-um > salt-are) or what would have been the fourth principal part (insult-um > insult-are), if it existed. Such verbs denote repetitive or continuous action. This is why the verb saltare means "to dance," because dancing -- for the Romans, at least -- was an act of leaping and bounding continuously.
