An Etymological Dictionary of the German Language/Teppich
Teppich, m., ‘carpet, tablecloth,’ from the equiv. MidHG. and OHG. tęppī̆ch, tębech, m. and n.; borrowed probably in the 8th cent. from Romance. The variants OHG. and MidHG. tęppī̆d, tęppī̆t, point immediately to Ital. tappeto, Lat. tapêtum, or rather tapêt- (Fr. tapis). ModHG. Tapet, Tapete, and tapezieren are more recent loanwords; comp. Ital. tappezzare, ‘to paper’ (a room).
