originFrom Swiss French sérac (“kind of cheese; sharp tower of ice”), from Franco-Provençal sera, seré, from Latin seraceum, from serum (“whey”), from Proto-Indo-European *ser- (“to flow, run”). Sense 2 is from the resemblance of the towers of ice to the cheese, which tends to cleave into rectangular pieces.
