Old English brod "brood, fetus, hatchling," from Proto-Germanic *brod (cf. Middle Dutch broet, Old High German bruot, German Brut "brood"), literally "that which is hatched by heat," from *bro- "to warm, heat," from PIE *bhre- "burn, heat, incubate," from root *bhreue- "to boil, bubble, effervesce, burn" (see brew (v.)).
