Take the German word Mappe. 'Map' exists in English but, while you are talking about something to put papers in, your Englishspeaking business contact thinks you mean a large piece of paper with roads and towns on it (Landkarte). The correct English word for Mappe in this particular case is 'folder'. Other examples are Gift/gift, Kredit/credit, Fabrik/fabric. You will find a list of the more frequently heard false friends in the latter half of this book.
