Word History

Etymology

borrowed from Latin jūbilant-, jūbilans, present participle of jūbilāre "to let out whoops, invoke with shouts" (Late Latin, "sing hymns of joy, be joyous"), from *jū, jō, exclamation expressing strong emotion + -bilāre, as in sībilāre "to hiss"; *jū going back to Indo-European *i̯ū, whence also Middle High German jū, jūch, exclamation of joy, jūchezen "to rejoice," Old Icelandic ýla "to howl," Greek iȳ́, exclamation of amazement, iȳ́zein "to shout, yell"

Note: The meaning of the Late Latin verb has been influenced by jūbilaeus jubilee entry 1, which itself has been influenced formally by jūbilāre.
