What Alessia Means
Alessia means defender or protector, from the Greek verb alexein, to ward off. The root is the same one that opens Alexander, where it is joined to a word for man to give defender of men.
Where Alessia Comes From
Alessia is the Italian feminine of Alessio, from the Greek Alexios, built on alexein, to defend or ward off. Saint Alexius, a fifth-century ascetic who reportedly lived unrecognized as a beggar in his own family's house, carried the name through the Byzantine and then the Latin church, and several Byzantine emperors bore it. Italian shortened Alexios to Alessio and formed Alessia alongside it. The same root gives Alexander, defender of men, and Alexandra. On record Alessia appears from 1967 and has risen with the broader English-speaking taste for Italian names.
