Male Ukrainian name (Олексій)
Oleksii (Ukrainian: Олексій) is a male name of Greek origin meaning «defender», «helper», «one who defends» — sharing the same root as Oleksandr.
The name derives from Ancient Greek Ἀλέξιος (Aléxios), formed from ἀλέξω (alexō, «to defend, ward off»). In the Greco-Byzantine onomasticon several emperors of the Komnenian dynasty bore the name (notably Alexios I Komnenos, 11th–12th century). It entered Christian tradition through Saint Alexius, Man of God — a Roman ascetic of the 5th century especially revered in Eastern Christianity. The Ukrainian form Oleksii is native, with the characteristic initial «o-» replacing the Greek «a-». The name appears repeatedly in the history of Ukrainian Christianity and culture.
From Ancient Greek Aléxios («defender, helper»), from the verb alexō («to defend»).
