Luca

Usually interpreted as “from Lucania”

Luca is the Italian masculine form of Lucas or Lukas, usually explained as “from Lucania”, a historical region of southern Italy. This interpretation comes through the older forms Lucas and Loukas; the deeper derivation is not completely certain. The final a belongs to the Italian boys’ name. There is also a Hungarian girls’ name written Luca, but it comes from Lucia and has a different pronunciation. The shared spelling therefore does not tell the whole story about origin or use. In Italian, Luca has a long u sound, a clear k and an open a, with the stress at the start. That movement gives it a warm, lively feel without much ornament. Compared with Lucas, the open ending offers a gentler finish, which may be the detail that makes Luca more appealing to your ear.

Etymology: The Italian form of Lucas, through Latin Lucas and Greek Loukas; usually linked to Lucania in southern Italy.
