iubeo

• jubeō

From Old Latin ioubeō, from Proto-Italic *jouðeō, from earlier *jouðejō, from Proto-Indo-European *Hyowdʰ-éye-ti, causative of Proto-Indo-European *Hyewdʰ- (“move upright”), likely an extension of *h₂ey- (“life, age”). Indirectly cognate with iūrō and iūs, aevum and iūgis, and possibly with imitor and imāgō.

• (Classical Latin) IPA^(key): /ˈi̯u.be.oː/, [ˈi̯ʊbeoː]

     sī quibus ēiectus silvīs aut urbibus errat.”

¹At least one use of the archaic "sigmatic future" and "sigmatic aorist" tenses is attested, which are used by Old Latin writers; most notably Plautus and Terence. The sigmatic future is generally ascribed a future or future perfect meaning, while the sigmatic aorist expresses a possible desire ("might want to"). It is also attested as having a rare sigmatic future passive indicative form ("will have been"), which is not attested in the plural for any verb.
