Meaning and history
Vadik is a Russian masculine diminutive, most commonly of Vadim. The origin of Vadim is uncertain; it may derive from a Slavic root connected with accusation, dispute, or knowing, but competing explanations exist. Vadik is normally informal and affectionate rather than a formal birth-certificate form. Saint Vadim of Persia gives the full name an Orthodox Christian association. Prominent public figures usually appear under Vadim, so reliable notable bearers using Vadik officially are limited.
