Petrovski is a Macedonian surname derived from the given name Petar, the Macedonian form of Peter. The suffix -ski is a common possessive suffix in Slavic languages, and in surnames it often indicates origin or lineage, equivalent to 'of' or 'belonging to'. However, in this context, the suffix is used in its patronymic sense akin to '-son', making the name literally mean "son of Petar". Surnames in this form are particularly common in Macedonia and other South Slavic regions. The name Peter, from which Petar and eventually Petrovski is derived, has deep Christian roots. Originating from the Greek Πέτρος (Petros) meaning "stone" or "rock", it was the name given by Jesus to the apostle Simon, as recorded in the New Testament (Matthew 16:18, John 1:42). Simon Peter became a foundational figure in Christianity, considered by many traditions as the first pope. The name spread across the Christian world and evolved into numerous local forms. Surnames based on patrons or place names—such as place-names suffixed with -oevoc/oeva as in the Russian-Patronymym that descended—have remained, including the inherited forms where '-ov' or '-ski' indicate affiliation. The archaic form Pandev (seen as a variant) shows phonological change from the base Petar ('pet- > [pand- in Bulgarian/Macedonian diminutive?
