Don't worry, ""Leegduutse"" is fine, most speakers of standard Dutch don't know (exactly) what it means anyway.

I still have 1 more question though, you used ""taeln"" for ""languages"". I was wondering, could this be a Low Frankish (Nederfrankische) loan to your dialect? Low Saxon wikipedia seems to use only ""Spraak/Spraken"".
