Uiecha (1940). A city in the Bryansk region. The name is given from the Unecha River, on which the village was founded in 1672. It is possible to see in this name the Proto-Slavic form * unetja, known in the Old Russian root un - "young" (Toporov, Trubachev. Linguistic analysis of toponyms of the Upper Dnieper region). Young in relation to a water source can mean "young, new, or recently emerged", possibly as a result of a change in the course of the receiving river or other circumstances. Opposite hydronyms with the root star- (Staritsa river, lake. Starorechye, etc.) as remnants that indicate the former, old riverbed. unechtsy, unechets unechsky district,- th, - th Unzha.

The hydronym is associated with the Baltic (Latvian, Lit.) ire "river"," stream": Lielupe, Peterupe, etc. Fasmer believed that if the hydronym was based on this appellative, then on East Slavic soil it would have the form Vop (compare the Vop river in the Upper Dnieper region). V. A. Nikonov eliminated this argument, relying on N. S. Trubetskoy's hypothesis about the dialect development of u > v > u > u, according to which the Russian word " Vop " is used in the Upper Dnieper region. Ban (Vop) could take the form of Upa (Nikonov.
