Pronunciation
Forms
iubeō (present infinitive iubēre, perfect active iussī, supine iussum); second conjugation[1]
Etymology
It is inherited from Proto-Italic *jouþ-eje/o-, inherited from Proto-Indo-European *Hioudʰ-eie/o- (“to cause to move”), a causative.[2][1] The oldest form ⟨ioub-⟩, found in early inscriptions, fits this type, and ⟨iub-⟩ was taken from the perfect and participle.[2][3] Cognate with Ancient Greek ὑσμίνη (husmínē, “battle”) and Lithuanian judėti (“to move”).[2][3] Lewis and Short suggested *iūs habēre “to regard as right”, an idea not followed by de Vaan.[4][2]
Earliest recorded meaning
De Vaan dates it from Livius Andronicus.[2] Köbler places his career before 200 BC.[5] Early inscriptions spell it ioub- and ious-.[3]
Semantic evolution
It meant to order or tell someone to do something, to order a thing to be done, and to direct, enjoin or appoint.[3] In the assemblies it was the word for enacting a law, in the formula velītis iubeātis, and for appointing a magistrate; laws, fate and duty were also said to command.[3] Its participle iussum meant an order.[3]
Döderlein distinguishes iubēre, bidding by one's own wish, the opposite of vetō, from imperō, commanding with military authority, and praecipiō, enjoining as a teacher.[6] The stem iuss- gave the grammatical term English jussive (1825).[7]
Timeline
