Word History



Middle English grut, grout "crushed grain for malt, infused malt, thick, dark ale, mud, slime," going back to Old English grūt "coarse meal, dregs, spent malt after brewing," going back to Germanic *grūta- (whence also Middle Dutch grute, gruut "herb mixture used in beer brewing," Middle High German grūz "a grain, grain of sand"), lengthened zero grade noun derivative from *greutan- "to grind, crush" — more at grit entry 1

Note: Sense 1, which first appears in the seventeenth century, is of uncertain relation to the earlier senses and perhaps of independent origin. Oxford English Dictionary, first edition, suggests a connection to Middle French (Limousin) grouter "to rough-cast," Limousin Occitan greutā, but this isolated word, itself of unknown origin, is of unlikely relevance.
