This name is likely a shortened form of the Ukrainian word "рот," which means "mouth." This assumption is supported by the prevalence of the surname Rot in documents from the 14th to the 16th centuries in Ukraine and Poland. For instance, in 1462, "on behalf of the Tatars... Stefan Rot" is mentioned in the city of Suceava (SSUM II 304); in 1666, "Ieronim Rot" is recorded (Arch YZR II/2 192); in 1680, a serf named "Jo. Roth" from the village of Richka is noted (Belay 183). Additionally, there is an example from Poland: in 1403, "Hanus Roth" appears (SSNO IV 493). However, considering the etymological nature of the name Hanus in connection with the anthroponym Roth, one can conclude that Rot is more likely a Germanism rather than a Slavism, as suggested by the Romanian researcher Iordan (Iordan 391).The Slavic etymological affiliation of the name Rot is supported by numerous derived forms recorded in the 15th to 16th centuries. Among them are the anthroponym recorded in 1565 as "Rotko Klymicz" (OKZR III 148); in 1600, "Ivan Rotko" from the Peresopnytsia district (Arch YZR I 2 99); and "Rotka Romanov" in 1600 (PK 224), among others.
