Ah! So is 'Mam-gu' grandmother and 'Nain' nan?
Nain is north wailian, and mam-gu is south wailian
But you will find people in the 'south' and the 'west' who also call their mam-gu 'Nain'!
Beth ydy lluosog mam-gu? mamau-gu?
'mam-guod' neu 'mamau cu'
Does it always use a hyphen. We never did when we wrote Mamgu on any cards to my Grandmother
Mam-gu is the usual dictionary spelling (it gives an indication of stress on the second syllable). Nevertheless, people do often write mamgu. (Similarly with tad-cu / tadcu.)
Definitely sounds like mamy-gu to me. Is this a variant or an artefact of the speaking robot?
Just a bit of a click in the TTS.
