Alexius
Primarily a girl's name of Greek origin with 1,515 recorded births. Also given to 135 boys.
Meaning & Origin
A male given name from Ancient Greek.
Alexius is a baby name of Greek origin, the Latinized form of Alexios, derived from the Greek alexein meaning 'to defend' or protect. It was borne by several Byzantine emperors, most notably Alexios I Komnenos.
Alexius shares its roots with the popular Alexander and Alexis, carrying a more classical, formal weight. It's a name with deep historical gravitas — rare in everyday use but immediately recognizable as part of the great Alex- family.
EtymologyShow more
Alexius is built from 7 letters and three syllables — a mid-length form that balances memorability with distinctiveness. Within the Greek naming tradition, this length is typical of names that preserve their full historical form, carrying their etymology on the surface.
The interplay of consonants and vowels in Alexius creates its characteristic classical, dignified quality. Multi-syllable names often carry remnants of compound constructions — two or more meaningful elements fused together — even when the original components are no longer transparent to modern speakers.
