"The word gravlax comes from the Northern Germanic word gräva/grave ('to dig'; modern sense 'to cure (fish)') which goes back to the Proto-Germanic *grabą, *grabō ('hole in the ground; ditch, trench; grave') and the Indo-European root *ghrebh- 'to dig, to scratch, to scrape',[3] and lax/laks, 'salmon'."
