bird

Origin

From Middle English bird, brid, from Old English bridd (“chick, fledgling, chicken”), of uncertain origin (see Old English bridd for more). Originally from a term used of birds that could not fly (chicks, fledglings, chickens) as opposed to the general Old English term for flying birds, fugol (modern fowl). Gradually replaced fowl as the most common term starting in the 14th century. The "booing/jeering" and "vulgar hand gesture" senses derived from the expression “to give the big bird”, as in “to hiss someone like a goose”, dated in the mid‐18th century.
