Gracious and light
A rare compound name of Italian origin, combining Gianni (a diminutive of Giovanni) and Lucas. It merges the meanings of divine favor and the illumination of light. While Gianluca is the standard Italian form, the addition of the 's' is an occasional stylistic variation found in Portuguese-speaking regions or as a modern creative adaptation.
