The personal name "Peresul" originates from Polish and Ukrainian records of a two-rooted name for the same Galician village, documented in 1578 as "Przsułowice" and in 1676 as "Peresołowice." The village name is derived from a personal name with an adjectival base "-sul-", which means "stronger" or "better," with the prefix "pere-" indicating an increased degree of the expressed characteristic. It is also worth noting that there are Czech names "Nesul," "Samosul," and "Vsesul."
