Commentary

The sequence -ou is perhaps a spelling for the Celt. ending -ū of the nom. sg. of the on-stems. Either, this originally monophthongic ending developed really into the diphthong /-ou̯/, or the spelling is an orthographic compromise between the vernacular ending -ū and the Latinised ending -ō. Cp. the legend coppou beside coppo on Noric coins.
