Konstantinus is the learned, Greek-influenced Latin form of a name ultimately from Latin Constantinus, built on constans “steadfast, faithful.” The initial K mirrors the Greek Κωνσταντῖνος (Konstantinos), and appears in medieval and ecclesiastical Latin where Greek models were strong. As a -us masculine nominative, it has a formal, classical flavor often found in baptismal registers and hagiographic texts.

Usage spread widely after Emperor Constantine the Great (4th century) and through numerous saints and rulers, securing the name across Christian Europe. Common cognates include Konstantin (Slavic, German), Constantin (French, Romanian), Constantine (English), Constantino/Costantino (Spanish/Italian), Constantino (Portuguese), and Konstantinos (Greek); the strictly Latinized Constantinus also occurs. Diminutives and short forms include Kostya (Russian), Kostas/Costas (Greek), Costa, Connie, and Tino. Feminine counterparts are Constance, Constantina, and Konstantina. Overall meaning centers on constancy, reliability, and steadfast devotion.
