The Eggy History of Brood

One of the noun senses of brood that is often encountered today is "the children of a family" (as in "they showed up at the picnic with their whole brood"). This may seem as though it is unrelated to the most commonly used verb sense, which is "to think anxiously or gloomily about; ponder," but the two words come from the same source, the Old English brōd. The noun form of brood came first, and the verb, when it appeared in our language, was used to refer to the action of chickens sitting on their eggs. Eventually the verb began to be used in a figurative manner, and took on the "worriedly pondering" sense it has today.
