The name may be derived from the word korost, 'brushwood, bushes, shrubbery'; the form Iskorosten sometimes found in early sources is probably based on the common repetition of prepositions in Old East Slavic: iz grada iz... 'from the city from...'. Another theory holds that the city was built entirely of wood, and its walls were surrounded by an oak fence, unhewn, with bark, leading to the name Is-koro-sten, i.e. the city "from bark on the wall" in Ukrainian.

All your cities have surrendered to me and submitted to tribute so that the inhabitants now cultivate their fields and their lands in peace. But you had rather a tide of hunger without submitting to the tribute.” The Drevlians responded
