An Etymological Dictionary of the German Language/Leich
Appearance
Leich, m., ‘lay,’ a term borrowed anew from MidHG. leich, m., ‘song consisting of unequal strophes,’ orig. in a general sense ‘instrumental melody’ (whence OFr. lai was borrowed). It corresponds to Goth. laiks, ‘dance,’ from laikan, ‘to dance,’ AS. lâc, n., ‘play, tilting,’ from lâcan, ‘to leap, dance.’ Since ModHG. Leich is only a loanword, no further remarks are necessary concerning the specifically OTeut. root laik and its wide ramifications.
