Rut was attested in historical sources as
Corithnich Reutharius in 1310,
Cordnitze super Tulminum in 1480,
Krytha bey der Pfarr in 1515,
Coriniza di Baza in 1566, and
Teutsch Coritniza in 1624, among many other names. It was labeled
D. Ober Koritniza oder Deutsch Greuth in the late-18th-century
Josephinian Land Survey. The Slovene name
Rut is derived from the Slovene common noun
rut, referring to a meadow on cleared land in a hilly environment. The Slovene noun is a borrowing from Middle High German
rut 'clearing'. The older name of the village,
Nemški Rut (literally, 'German Rut'), refers to the community of German speakers that formerly lived there. The Slovene name of the village was changed from
Nemški Rut to
Rut after the Second World War ==Church==
