Even after hearing this twice I was unable to decipher what she was saying ( I totally understand the sentence when I see it) I learned to pronounce "raibh" ending with a "v" sound - she seems to use a "w". Is this a regional thing?
Yes - raibh is "rev" in Munster, and ranges from "ruh" to "row" (as in argue) in other dialects.
No going is ag dul. Chun means i will. Like: Tá mé a chun mo h-íolacha a ceangailt
You could as easily ask where is the motion implied by the verb "go" in the English sentence?
As "go" in the English sentence is not a verb of motion, you don't need a verb of motion in the Irish sentence, and the preposition chun plays the same role of indicating intention in the Irish sentence that "going" does in the English sentence.
