Would "Dw i isio siocled rŵan" be ok here, as the chapter is about dialects, or is isio too informal?
Dwi isio siocled rŵan! was accepted. ;)
Ond doedd ddim siocled yma i mi.
When should I use rwan instead of nawr? I am just guessing at the moment.
Both rŵan and nawr mean 'now'.
The more standard word is nawr, but rŵan is very common in a number of mid- and north Wales dialects.
