*aukô

A masculine n-stem from the root *auk- of *aukaną, ultimately from Proto-Indo-European root *h₂ewg- (Orel 2003: 29; Rix et al. 2001: 274–75). Its deeper antiquity is uncertain: Wodtko and colleagues (2008: 328–29) list the Germanic formation as *h₂áu̯g-e/on-. Bammesberger (1999: 23–31) proposes an inherited PIE *aug-ō(n)-, comparing Celtiberian auku, which he glosses as approximately ‘yield, produce’, but Prósper (2006: 144–46) argues that Celtiberian auku instead continues the PIE neuter u-stem adjective *h₂eug-u- and that the inherited PIE noun was the s-stem *h₂eug-os-; on this analysis the Germanic n-stem is an innovation. Compare the root-related Latin augmen. No secure exact non-Germanic cognate of the n-stem is known.
