An Etymological Dictionary of the German Language/Annotated/Prahm
Prahm, masculine, ‘ferryboat, punt,’ Modern High German only, borrowed from Low German; compare Dutch praam, ‘transport,’ Danish pram, Old Icelandic prámr, English prame. The whole of the cognates are derived from Slavonic; compare Slavonic pramŭ, which is connected with the Aryan root par, ‘to carry across,’ preserved in High German fahren (Old High German faran).
