Origins of Tannin

'Tannins' are a class of chemicals that bind to proteins. Many plants produce tannins, including the oak species I'm studying this summer. The name 'tannin' comes through French from the Latin 'tannum,' which means 'oak bark.' The German word 'tannenbaum'  (Christmas tree) is apparently related; 'tanne' means 'fir' and 'baum' means 'tree.'
