vaticinor

Etymology
From and. The change from to  follows the common pattern of Latin vowel reduction in non-initial syllables. As is a third-conjugation verb, the derivation of first-conjugation  may involve more steps than simple compounding of the base noun and verb; many first-conjugation verbs are denominative (derived from nouns or adjectives), and it has been hypothesized that an intermediate step in the derivation of  was a compound noun.

It is also hypothesized that this verb was the original basis from which the ending was extended by analogy to be used as a suffix to form other verbs, such as  and.
