"With a million pounds."
Translation:Gyda miliwn o bunnoedd.
What's the difference between Efo and Gyda, do both mean with and how would you use each of them?
Both mean 'with', especially in the sense of 'together with'.
efo is more commonly used in north and north-west Wales, gyda more in mid, south and south-west Wales, although with quite a lot of overlap.
