Koritno was attested in written sources circa 1065 as Corithna, circa 1075 as Coritno, in 1287 as Goriten, and in 1431 as Kareitten. The name is truncated from *Koritno selo, with an adjective derived from korito 'trough; riverbed, channel', referring to a landscape feature, plus selo 'village'. The Slavic root *kory̋to is a frequent basis for place names, such as Korita, Coritis (in Italy's Resia Valley), Korito (in North Macedonia), and Korytná (in the Czech Republic).[2]
