Commentary

Most likely an abbreviated personal name, though no immediate Old Celtic comparanda are available. Stifter 2010: 372 tentatively suggests a first element diu̯o- (Stifter 2024b: ? *diu̯- 'day, sky, divine', e.g. ⁺diumaros uel sim., but usually dio-, see dēu̯-) or dī- 'from' (with unidentifiable second element). See also Salomon 2024: 168.
