An Etymological Dictionary of the German Language/Blust

by Friedrich Kluge

Blust, m. (Suab. and Swiss, bluešt, n.), from the equiv. MidHG. bluost, f., ‘blossom'; Goth. *blôs-ts is connected perhaps with the Aryan root bhlôs, ‘to bloom,’ preserved in AS. blôs-tma, Lat. flôrere (for *flôsere). See Blume and Blüte.
