gradior

Latin

From Proto-Indo-European *gʰredʰ- (“to walk, go”). Cognate with Old Irish do·grē, Welsh grynnyaw (“to press, thrust”). The traditional connection of Proto-Slavic *gręsti (“to go”) (Old Church Slavonic грѧсти (gręsti, “to come, walk, go”)), Lithuanian gridyti (“to go, wander”), and Proto-Germanic *gridiz (“step”) (Gothic 𐌲𐍂𐌹𐌸𐍃 (griþs)), Old High German crit) is contested, as the Germanic and Balto-Slavic forms, as well as Old Irish ad·greinn (“to track, follow”), seem to trace back to a different root, Proto-Indo-European *gʰridʰ-, instead.^[1]
