"I'm Sioned."

Translation: Sioned dw i.

[adriennesls]

Why is it not? "Sioned ydw I" is it the differentiation in the dialect?

[EllisVaughan]

"Ydw" would be wrong here since ydw is not the same as dw i.

[areddragon]

We were taught "Name ydw i"/"Name ydy fy enw i" in my school, what's the difference?

Edit: Ellis was right about "Name ydy fy enw i"

[EllisVaughan]

Well it might be in some dialects but I have never seen ydw/yw used in the emphatic. Also it should be "Name ydy/yw fy enw i" for the second one you put. Ydw is only used for the first person.

[areddragon]

Yeah, I think you're right about the ydw fy enw i. I expect it's dialect with the emphatic, but I'll check my old notes when I get home to make sure I'm not misremembering.

Edit: Yeah, checked, we were taught "Name ydw i" in my school in South Wales.

I think it's a difference in dialect, we were taught "Sioned ydw i" in my school.
