When do use dw i vs. dw i'n
I don't really see a pattern here. Can someone help me out?
As others have mentioned 'dw i'n' is used with every verb (and adjective). Dw i is used with 'eisiau' and 'wedi' and also in emphatic sentences like 'athro dw i' (I'm a teacher), and 'Megan dw i' (I'm Megan). With hindsight we should have left the 'dw i' sentences until later to avoid the confusion. It'll probably be one of the changes in Tree 2.
