Giannou Surname Meaning
The Greek surname Giannou (Γιαννού) is a patronymic surname preserved in the genitive form, meaning “of Giannis.” It derives from Giannis (Γιάννης), the familiar form of Ioannis (Ιωάννης), meaning “God is gracious.” Genitive form surnames were commonly used in Greek naming tradition to indicate family or household association rather than direct descent from a single ancestor. As these identifiers were recorded in church and civil documentation, they became hereditary surnames passed through generations. The grammatical form remained stable even after its original possessive meaning faded from everyday awareness. Consequently, the surname Giannou signifies “the family of Giannis,” reflecting patronymic lineage rooted in traditional naming structure rather than occupation.
