..a' dol a ràdh
After a' dol, a' tighinn, a' falbh etc (verbs of movement) where you are implying 'purpose', i.e. going somewhere to do something, you use the lenited verbal noun with 'a' before it. If there's an object it somes after that, i.e. no inversion. If it's a definite noun ('the'), it is (officially) in the genitive.
Tha mi a' dol a dhunadh an dorais.
Tha mi a' tighinn a dh'fhosgladh na h-uinneige.
Bliadhna mhath ur!
