Arsenius is Greek in Origin.

Arsenius is the Latinized form of Greek Arsenios (Ἀρσένιος), from arsēn “male” and arsenikos “virile,” yielding the meaning “manly, strong.” Known in ecclesiastical Greek as a monastic name, it traveled into Latin hagiography and Western records while retaining its Eastern character.

The name gained prominence through Saint Arsenius the Great (c. 350–445), a Roman tutor turned Desert Father in Egypt, and later saints such as Arsenios of Cappadocia, anchoring its use in Byzantine and Eastern Orthodox traditions. Medieval usage concentrated in the Greek‑speaking world, spreading into Slavic and Caucasian languages; today it appears as Arseny/Arseniy (Russian), Arsenii (Ukrainian), Arsenije (Serbian), Arsen (Armenian, Georgian, Balkan), and Arsenio (Italian, Spanish, Portuguese). Diminutives include Arsen and Senya in Slavic contexts. In English, Arsenius remains rare but scholarly and ecclesiastical, while the Romance form Arsenio has wider modern recognition (e.g., Arsenio Hall). The name evokes a classical, ascetic strength with deep Christian resonance.
