Luca

Often associated with the Italian form of Lucas; sometimes linked in popular explanation to "light", though that isn’t the only etymological path.

Luca is a masculine given name that’s firmly established in Italian usage and now common internationally. It reads simple and contemporary in many languages, partly because it’s short, phonetic, and uses familiar letters. Etymologically, Luca is usually treated as the Italian form of Lucas. Many references connect Lucas/Luca to the Latin Lucanus, meaning "from Lucania" (a region in southern Italy). You may also see "light" mentioned in popular summaries; it’s best read as a modern association rather than a single guaranteed root. Pronunciation is commonly LOO-kah, in two syllables, with a clear "oo" sound at the start. A practical tip is that English speakers sometimes vary between LOO-kah and LOO-kuh; if you care about the final vowel, the Italian-style -a is the usual target.

Etymology: Italian Luca is traditionally treated as a form of Lucas, ultimately connected in many references to Latin Lucanus ("from Lucania").
