If you live in Hamburg for longer, you will probably hear some very strange words (apart from the usual strange German words ). Some of them might sound quite familiar, though.
Plattdüütsch, also: Plattdütsch (= Plattdeutsch = low German/flat German) is being spoken in many areas, most active in Schleswig-Holstein, Hamburg, Niedersachsen. But you will also find it in the Netherlands, Denmark, even parts of Poland.
Living in Hamburg you should know some basics, which I would like to collect here...
...and start with the most important word:
moin = hello
moin moin = (have a) good day
