iubar

Latin

Etymology

Uncertain:

• From Proto-Italic *djuβās, from Proto-Indo-European *dyew-bʰeh₂-es- (“bringing the light of daytime”, literally “sky-shining”), from *dyew- (“sky, heaven”) (whence Latin diēs (“day”)) and *bʰeh₂- (“to shine”) (whence Ancient Greek φάος (pháos, “light”)).
• From Proto-Indo-European *Hyéwdʰ-r̥ from the root *Hyewdʰ-, from which also iubeō, directly cognate to Ancient Greek εἶθαρ (eîthar, “at once”).

Pronunciation

• (Classical Latin) IPA^(key): /ˈi̯u.bar/, [ˈi̯ʊbär]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈju.bar/, [ˈjuːbär]
