Gennadius is Greek in Origin.

Gennadius is the Latinized form of Greek Gennadios (Γεννάδιος), derived from the adjective gennaíos, “noble, brave, generous,” ultimately tied to génos, “birth, lineage.” The name thus conveys ideas of high birth and valor along with magnanimity, a cluster of virtues prized in classical and Christian contexts.

It gained currency in the Greek-speaking church and Byzantine world, borne by figures such as Patriarch Gennadios I of Constantinople (5th century), Gennadios II Scholarios (15th century), and the presbyter Gennadius of Massilia. Through Orthodox tradition it entered Slavic usage, producing variants like Gennady/Gennadiy (Russian), Hennadiy (Ukrainian), and Henadz (Belarusian); Greek retains Gennadios, while the Latin Gennadius appears in ecclesiastical records. A rare choice today in the West, it carries a distinctly scholarly, antique aura.
