An Etymological Dictionary of the German Language/dämisch

by Friedrich Kluge

dämisch, dämlich, adj., ‘dull, drowsy, crazy,’ ModHG. only; a MidG. and LG. word (Bav. damiš, taumiš); from a Teut. root þêm, equiv. to Sans. tam (tâmyati), ‘to get tired, out of breath,’ whence Lat. têmulentus, ‘drunk.’ Probably allied to the cognates of dämmern.
