Pronunciation

  • Classical: [ˈjuː.noː][1]
  • Ecclesiastical: [ˈjuː.no][1]

Forms

Iūnō f sg (genitive Iūnōnis); third declension[1]

Etymology

It is probably from Latin iuvenis (“young”): de Vaan lists the goddess among the derivatives of that word and takes the name as a separate extension of a stem ⟨iūn-⟩ “young”, the stem of iūnior.[2] The word goes back to Proto-Indo-European *h₂iu-h₁en- (“who possesses vital force, young”).[2] Georges and Walde also explain her as “the young, blooming one”, and Walde holds that her link with Iuppiter is secondary.[3][4] Rix takes Etruscan uni for a borrowing of an early Latin form of the name.[2]

Wiktionary gives a second view, a derivation from Proto-Indo-European *dyew- (“sky, heaven”), like Ancient Greek Διώνη (Diṓnē).[1]

Earliest recorded meaning

De Vaan records the name from Plautus on,[2] who has a husband call his wife “my Juno”.[5] Köbler lists the Carmen Saliare and the Twelve Tables among its first sources.[6]

Semantic evolution

Juno was the wife and sister of Jupiter, identified with the Greek Hera,[5] the queen of the gods and the goddess of marriage and of women.[3][7] She had many cult titles, such as Moneta, Sospita and Regina;[5][3] as Iuno Lucina she was the goddess of childbirth,[5] and Iuno inferna was a name for Proserpina.[5] Each woman had her own Iuno, a guardian spirit like a man's genius, by which women swore.[5][3] The peacock was Iunonis avis and the planet Venus Iunonis stella.[5] Varro and Cicero report the philosophers' interpretation of Juno as the air.[3]

Medieval writers kept this reading and took Juno as the lower air, Jupiter being the upper.[8] In New Latin the name was given to an asteroid.[1] Italian Giunone continues the name.[9]
