An n-stem is unambiguously attested in the majority of Slavic languages, including importantly Old Church Slavonic. The East Slavic languages reflect an extended neuter n-stem *polymę or (for Ukrainian) *polumę instead. Russian has loaned the OCS form but converted it into a neuter n-stem as well. The modern Bulgarian form, although clearly related, has a different suffix, reflecting *polmъkъ.
