beech (n.)

O.E. bece "beech," from P.Gmc. *bokjon (cf. O.N. bok, Du. beuk, Flem. boek, O.H.G. buohha, Ger. Buche, M.Du. boeke "beech"), from PIE base *bhagos "beech tree" (cf. Gk. phegos "oak," L. fagus "beech," Rus. buzina "elder"), perhaps with a ground sense of "edible" (and connected with the root of Gk. phagein "to eat;" see -phagous). Beech mast was an ancient food source for agricultural animals across a wide stretch of Europe. Formerly with adjectival form beechen. Also see book.
