|Attestation:||VB·3.3 (lutou : iiii) (1)|
|Word Type:||proper noun|
|Semantic Field:||personal name|
|Morphemic Analysis:||lut-ū Attention, needs to be checked!|
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. See also lutu, lutuu.
