<p>Alexios is traditionally a masculine Greek name, though used here as feminine. It derives from the Greek word 'alexein' meaning 'to defend' or 'to help,' sharing roots with Alexander. With ancient origins, Alexios appears in Byzantine history, notably Emperor Alexios I Komnenos. The feminine usage represents a modern trend of adapting traditionally male names for girls. While uncommon for girls, it offers the familiar nickname Alex, which works across genders. Alexios carries a classical sophistication with its Greek heritage and -os ending. Though rare for girls internationally, it might appeal to parents of Greek heritage or those seeking a strong, distinctive name with historical depth.</p>

Alexios is occasionally used for boys in 2025.
