An Etymological Dictionary of the German Language/Gefäß
Gefäß, n., ‘vessel, receptacle,’ from the equiv. MidHG. gevœȥe, n. (OHG. givâȥȥi, m., ‘transport’). Goth. *gafêti, n., is wanting; it would probably be connected with Goth. fêtjan, ‘to adorn’ (AS. fœted, partic., ‘adorned’), and also more remotely with Faß.
