Probably using a different word altogether - digyffro - especially if we mean relaxed as in calm about things:
- Pam rwyt ti mor ddigyffro? - Why are you so relaxed?
The use of mor for 'so' in this context is covered later in the course.
What does this mean? I'm a native English speaker and it seems a very stilted sentence
I think it means something like "Why do you spend so much time relaxing", but I'm not sure.
