Is it tegannau or teganau? The spelling seems to vary during the Welsh course. I do not know what to report, because I do not know which one is the correct spelling.
Thank you for a great course! :)
The standard spelling is with one 'n' but there are regional variations where the double 'n' is used.
The double consonant in some Welsh words is a controversial subject since they make no difference at all the pronunciation of the word and there is clearly a case for standardisation.
The present course has double 'n' as the main spelling while accepting a single 'n' as a acceptable alternative, the revised course will reverse that.
