An Etymological Dictionary of the German Language/Rausch

by Friedrich Kluge

Rausch (1.), m., ‘cranberry,’ from MidHG. rûsch, rusch, f., ‘rush,’ from Lat. ruscum, whence also Du. rusch, m., ‘rush,’ AS. rŷsče, f., E. rush; see Risch and Rusch.

Rausch (2.), m., ‘carouse, rush, roar,’ ModHG. only (corresponding in MidHG. to rûsch, m., ‘onset, attack’; see rauschen); its relation to LG. roes, ‘intoxication,’ E. rouse, OIc. rúss, ‘drunkenness,’ is still obscure. The ModHG. word has certainly been borrowed.
