The name "Prychyna" likely became a feminine name among Ukrainians, derived from the noun "prychyna," in which one of its meanings carries an archaic semantics of "unforeseen circumstance." As for the name "P'yatnytsia," it obviously became a feminine name due to the translation from the Serbian name for the fifth day of the week, "petka," which means "Friday." The Serbian "petka" is a calque from the Greek "Paraskēuē." This name is mentioned in 1552 in the Description of Kyiv Castle: "Ormensky popa dom, P'yatnytsia Chukhystynoe dom."
