An Etymological Dictionary of the German Language/Glanz
Glanz, m., ‘lustre, splendour,’ from the equiv. MidHG. glanz (wanting in OHG.), with which is connected the OHG. and MidHG. adj. glanz, ‘bright, shining’; ModHG. glänzen, from the equiv. OHG. and MidHG. glęnzen; to the same class belong MidHG. glander, ‘splendour, shining,’ and glanst, ‘splendour,’ further glinster, ‘splendour,’ and the very rare str. vb. glinzen. A stem glint- is wanting in the rest of the Teut. dialects unless the cognates of glatt (Goth. *glada-) are allied.
