The name Luca comes from the Latin Lucas, which in turn could be an abbreviation of Lucanus or an evolution of the Greek Loukas (Λουκάς), both indicating “coming from Lucania”.
Some scholars also hypothesize a link to the Greek noun Lyke, which means “born in the early morning,” giving the name an additional meaning.
Derivation and Meanings:
Lucania
The reference to Lucania, a region of southern Italy, suggests a link with the geography and historical origins of the name.
Light
The term Lucanus (and by extension “Lucas”) could also be connected to the Latin word lux (light), leading to a broader meaning related to enlightenment and clarity.
Lucio/Lucia
The name Luca is closely related to the names “Lucio” and “Lucia”, which come from Latin and mean light.

Idea and authenticity: horizon between potential and possible of which you do not have to fear being a victim, but the favorite target of those who do not live it.
(Luca Schifano)
