An Etymological Dictionary of the German Language/Truhe
Truhe, f., ‘trunk, chest,’ from MidHG. truhe (*trucke is indicated by dial. Trucke), OHG. truha (truccha), f., ‘chest, cupboard,’ OIc. þró (from þrū̆h), and AS. þrûk, ‘chest, drawer,’ seem to be allied in meaning although the sounds do not entirely correspond. In any case Lat. truncus, ‘trunk’ (of a tree) is not allied. If AS. þrûh is not identical with HG. Truhe (MidLat. trucca), the latter may be connected with Trog; Truhe (lit. ‘wooden vessel’) would then be Aryan drū̆k- (drukn-).
