Italian male names primarily derive from Latin and Italian, often transmitted through Christian (especially Catholic) usage. A clear masculine marker is the final -o (Alberto, Aldo, Amedeo), with some masculine forms ending in -e (Alessandre is nonstandard; Alessandro is the standard masculine form). Diminutive or hypocoristic forms with -ino appear in male names such as Albertino. Female counterparts typically take -a (e.g., Alessandra), while the male forms use -o.

Traditional male naming has been strongly influenced by saints, popes, and classical figures. Modern use favors established, easily recognized choices; from the list, more common options include Alessandro, Alessio, Alberto, Aldo, Amedeo, and Alfio.
