The original form of the Russian river name Volkhov should be reconstructed as *Vǔlxy belonging to the ancient declension type with *-ū. The stem *Vǔlx- comes from IE *uel-/*uol-(/*uōl-)/*ul- ‘roll’, ‘attract’. This etymology is proved both by historical attestations and numerous parallels. The hydronym Vorskla (< Vǔrǐsk(ǔ)lǔ, as attested in the earliest source) is explained as a derivative with the suffix -l from the quantitative phonetic variant of the stem vǔrīsk- (Old Russian vǔrīskanie ‘horse competition’ from rīskati ‘run’, ‘go quickly’, ‘jump’, ‘rush along’, ‘aspire’). This variant of the stem is also attested in the Czech village name Vrskmaň.
