- English: mere
From Proto-Germanic *mērijaz (“famous”), from Indo-European. Cognate with Old Saxon māri, Old High German māri, Old Norse mærr. The Proto-Indo-European root is also the source of Greek -μωρος (in ἐγχεσίμωρος (enkhesímōros) ‘mighty with the spear’), Old Irish már (Scottish Gaelic mòr, compare claymore), Welsh mawr (“big”).
Germanic mār-, mǣr- is also used in Germanic given names, such as Swedish Ingemar, English Aylmer, Italian Ademaro, German Dietmar, French Omer etc. Its Indo-European ancestor is conserved in Old Slavonic мѣръ (měrъ/měrŭ), as in the Russian given name Владимир (Vladimir), and in Gaulish given names as Segomārus and Viridomārus.
