In the Slovenian toponyms Rítoznoj and Ritoznoje, as well as in the Serbian R``itopek, Slavic deverbal compounds *r˝ito-znojь/-znoje and *r˝ito-pekъ have been preserved. They originate from the syntactic constructions *(kъde sъlnьce) *znojítъ/ pečètъ (vъ) r˝itь (gory/vъzpętiny) ‘(where the sun) blazes down on the back side (of the mountain/hill)’. These compounds have been used to denote – like the synonymous compound *čelopekъ – besides the sunny side of the locality (*-znojъ/-pekъ) in their first part *rito- ‘the rear side’/*čelo- ‘the front side’ also the direction from which the sun blazed down with regard to the topographic object, i.e. the mountain/hill as a whole. Both compounds can therefore testify to an even earlier settlement of the areas to the west of the contemporary settlements of Rítoznoj, Ritoznoje, R``itopek, and to the east of the contemporary settlements of SSlav. *Čelopekъ.
