[Wiktionary-l] Nyanja and Tswana

[Gerard Meijssen]

Hoi,
In a recent post I wrote the ISO-639 codes for Nyanja and Tswana. The 
information although correct was not complete; they have both two and 
three character codes within ISO-639.

Nyanja or chiChewa has ny and nya
Tswana has ts and tsn

For use within Wikimedia projects we always use the two character codes.

Thanks,
    GerardM
