According to E. Rossoni, Armone derives directly, or through Italianised forms, from the Hebrew name Armon or the old Lombard name Armone. The surname belongs to the group of patronymic surnames formed from personal names widespread during the Middle Ages.

V. Blunda attributes a Germanic origin to the surname and relates it to the personal name Armone, linked to the root arm, associated with the "arm" and, by extension, with the strength of the armed arm. He also notes that the Italian suffix -one has an augmentative value, so the name could have expressed strength, vigour or warrior qualities.

Blunda stresses that the surname is preserved especially in areas of southern Italy that received Lombard influence, where names of Germanic tradition had a significant diffusion. In this context, the element related to the armed arm constituted a symbol of strength and prestige within medieval Germanic anthroponymy.

Taken together, Armone is a surname of patronymic origin derived from an old personal name, probably of Lombard tradition, associated with ideas of strength, valour and warrior status.
