Costis Surname Meaning
The Greek surname Costis (Κωστής) derives from Kostis (Κωστής), a familiar form of Konstantinos (Κωνσταντίνος), the Greek equivalent of Constantine. Konstantinos derives from Latin Constantinus, based on constans, meaning “steadfast,” “constant,” or “firm.” The name became extraordinarily important throughout the Greek world because of Constantine the Great and subsequent Byzantine emperors and saints. Kostis developed as one of its traditional familiar forms. The surname likely originated from an ancestor commonly known as Kostis before his personal name became a hereditary family identifier through church records and generational continuity.
