Etymology

The word brooding originates from the Old English brōdan, meaning "to sit on eggs" or "to cherish warmth." Over time, it evolved metaphorically to describe deep, often melancholic contemplation, mirroring the patient, inward-focused nature of a bird incubating its eggs. The suffix -ing marks its adjectival or participial form, preserving the original spelling while extending its meaning.
