means A design technique where the image is carved or etched below the surface of a hard material, so ink or shadow fills the recesses rather than sitting on top.

from From Italian intagliare, 'to cut into' or 'engrave' — built from in- ('into') plus tagliare ('to cut'), the same root that gives Italian cuisine its tagliatelle, literally 'little cut things.' The word entered English in the 1600s alongside the gem-carving and printmaking techniques it named, where artisans gouged lines into copper plates or hard stones, letting the cut-away void do the work the eye reads as image.
