What does hoo mean?
“Hoo” is chiefly an informal interjection used to express rueful surprise, regret, or mild disappointment. A speaker might say “Oh, hoo, I see” upon realizing that an important appointment has been missed. The expression is especially familiar in British English but is understood in American English as well. It often suggests resigned amusement: the situation is unfortunate, but the speaker is not devastated by it. The word also has an older and more specialized noun meaning, a hunting cry traditionally shouted to encourage hounds to pursue game. Although that sense survives in dictionaries and historical accounts, it is rarely encountered in ordinary modern conversation. The interjection is therefore best understood as the dominant contemporary use, while the hunting sense explains the word’s distinctive sound and history.

“Hoo” preserves the old hunting cry once shouted to encourage hounds, while its modern interjection lets speakers neatly announce regret: “Oh, hoo, I see.”

Where does hoo come from?
The noun meaning “a hunting cry” comes from Middle English and is imitative in origin, reproducing the traditional shout used by hunters to encourage their hounds. The modern interjection expressing regret or rueful surprise developed from exclamatory uses associated with this cry and is now encountered chiefly in informal British English. Its sound is stable, and the word has no widely recognized set of exact cognates from which a longer family can safely be reconstructed.
