Giannakopoulos Surname Meaning

The Greek surname Giannakopoulos (Γιαννακόπουλος) is a patronymic name, meaning it is derived from the given name of a male ancestor combined with a diminutive form. The root Giannako- comes from Giannakis, a diminutive of Giannis (Γιάννης), the common Greek form of Ioannis, which originates from the Hebrew name Yochanan, meaning “God is gracious.” The diminutive conveys familiarity or affection and was widely used in Greek naming tradition. The suffix -opoulos is a patronymic marker that developed during the Byzantine period and became especially common in the Peloponnese and southern mainland Greece, meaning “son of” or “descendant of.” Consequently, the surname Giannakopoulos signifies “the son of Giannakis” or “the descendant of little Giannis.”
