miuca

Uncertain. Given the Asturian cognates (milu, meruca) and some current Galician (mioca, moca) and Portuguese forms (mioca), perhaps from *milo- + -oca, or *milokka, from a substrate language. The modern forms Portuguese minhoca and Galician miñoca are due to progressive nasalization, as minha, miña from Latin mea.

If related to or derived from Proto-Celtic *mīlom (“animal”), then from Proto-Indo-European *(s)meh₁l- (“small animal”).

*miuca f (plural miucas)

1. (Old Galician, hapax legomenon) earthworm
