KAMAHL: ono to kupodivu je opravdu totež.
From Proto-Germanic *bōks, whence also Old Frisian bōk (West Frisian boek), Old Saxon bōk (Low German Book), Dutch boek, Old High German buoh (German Buch), Old Norse bók (Danish bog, Norwegian bok), Swedish bok), Gothic 𐌱𐍉𐌺𐌰 (bōka). The Germanic root is often taken to be related to the word for beech, the wood of rune-tablets.
