I've seen chun used in places where i thought ag dul would be used for going to. How do you know when and where its supposed to be used like this?
Thanks. So could the first example use ag dul instead of chun by changing the structure to Tá sé ag dul ag ceannach carr nua amárach?
The first example where?
EDIT: Ah, at the link I’d provided (I’m slow on the uptake at times). No, carr nua needs to be genitive for the ag dul ag form — cairr nua — since in that form it becomes the object of the verbal noun ceannach.
