In the lessons, it sounds to me like they’re saying bydden/ basen i instead of byddwn/ baswn i. Am I missing something?
Yes you’re right. In Iestyn’s area they do say ‘en’. This has come up before and I have spoken to other first language speakers who also use this in West Wales…so it’s another example of ‘not from the text book’ but how it’s spoken regionally.
