"No, it is not foggy."
Translation:Nac ydy, dydy hi ddim yn niwlog.
I seem to remember being taught "Nag ydy" (with a "g" instead of a "c") as a child. Am I "misremembering" or is this another way to say it?
Thanks, ibisc! So, is this purely a pronunciation thing, or would it also be spelled "nag ydy"?
Just pronunciation. However, quite a few people write as they speak when writing informally, so you may see it written as well. I would avoid doing that while you are learning, though. to avoid confusing yourself!
This is explained in the notes for 'Present tense 3', a section that comes up shortly before this one.
Mae... is used to state that something exists or is happening. Dydy/Dyw... ddim... is its negative form when saying that something is not happening:
- Mae hi'n wlyb - It's wet.
- Dydy hi ddim yn wlyb - It is not wet.
can anyone tell me why na,dyw hi ddim yn niwlog has been marked wrong? thank you
The form of 'no' that is used depends on the question asked. Here it is most like to have been something like - Ydy hi'n niwlog o hyd? (Is it still foggy?) - and so the answer is Nac ydy...
(That said, you could probably devise an emphatic question which would justify the Na... form of 'No...', but it might not be a very natural-sounding one.)
