as the french like to call them "patates" even if "patates" is another root well it is approximately same thing but more sweet...
strange thing... well maybe not so strange... flemmish are influenced with wallon language i think...
flemmish has been greatly influenced by french, especially west-flemmish. Dutch however has also some words directly taken from the french, like "paraplu" or "punaize". Many believe those words to be dialect but they are correct Dutch and not the so called real ducth words repsectivly "Regenscherm" and "Duimspijker".
But what you gonna do about it?
