The personal name "Zbyn" originates from the truncated-suffix anthropo-base "zby/-", which is represented in compounds such as "Zbyhnev", "Zbylyut", and "Zbyslav", along with the suffix "-n". In the form of a katoykonim "Zbuna" (a village in the Volovets district of the Zakarpattia region), it is mentioned in a Latin record from 1648. In the local Ukrainian dialect, this name sounds like "Zbyn". In the Czech language, the colloquial equivalent of this name is "Zbynek".
