Proto-Celtic

Etymology

Cognate with the formally identical Proto-Germanic *maguz (“boy; servant”), apparently via Proto-Indo-European *mogʰus (“young person; boy-servant?”). Compare also Avestan 𐬨𐬀𐬖𐬀𐬬𐬀 (maγava, “unmarried”). Matasović notes that the /a/-vocalism of Gaulish Magu- is unexplained.

Noun

*mogus m

1. (male) servant
2. (male) youth, boy
