An Etymological Dictionary of the German Language/Griebs

by Friedrich Kluge

Griebs, n., ‘core of fruit,’ from the equiv. MidHG. grobiȥ, grübiȥ (also ‘larynx’), to which the dial. variants MidHG. grütz (gürbsi), ModHG. Gretzen, are akin. OHG. *grobaȥ and *grubiȥ are wanting; in form they are connected with OHG. obaȥ, ‘fruit,’ with MidHG. ebiȥ, ebitz, ‘core of fruit,’ and with ModHG. Butzen, as well as Swiss böki.
