Mayrhofer and others suggested a further connection with Ancient Greek αὖτε (aûte, “again”), ultimately from Proto-Indo-European *h₂u-te. This connection has been disputed by later scholars due to the difference in usage, but a direct PIE ancestor is still possible; Celtiberian [Term?] (uta) serves an identical function, and on this basis Klein reconstructs Proto-Indo-European *utá.
