The ancient Slavic male name Polk is derived from the patronymic Polkovich. This name originated from the shortened component "-pълкъ-", which means "crowd," from two-component names such as Svyatopol and Yaropolk. In Ukrainian records, this name is noted only in patronymics. For example, in documents from 1482-1491, there is mention of Yushka Polkovich, who received a volost. In Poland, the name Połk and its relatives have been mentioned since the 15th century. It is also worth noting the modern surname Povch.
