Etymology

The word "mood" traces back to Old English mōd, meaning "mind, spirit, courage," from Proto-Germanic mōdaz (source also of Old Saxon mōd, Old High German muot, Gothic mōds). Its semantic evolution reflects a shift from broader concepts of inner disposition (e.g., bravery) to specific emotional states. The grammatical sense arose in the 16th century, likely influenced by Latin modus ("manner, measure"), though the spelling remained unchanged.
