brood
UK: /bruːd/ | US: /bruːd/
n. 1. A family of young animals, especially birds, produced at one time.
n. 2. A group of children or young people raised together.
v. 3. To think deeply about something in a troubled or resentful way.
v. 4. (Of a bird) To sit on eggs to hatch them.
The word "brood" traces back to Proto-Germanic brōdą, meaning "that which is hatched." It originally referred to the warmth and care involved in hatching eggs, later extending metaphorically to nurturing offspring and, by the 16th century, to dwelling on thoughts (as if "hatching" them mentally).
