quote:Scots Gaelic is written more true to its actual pronunciation.
That's not true. In Gaelic there are many unpredictable things, maybe more than in Irish, in my opinion.
Go dtáinig is used by many Irish speakers, although it is not in the Standard Grammar.
In the Linguistic Atlas, there's a map about it ; actually it's about "why didn't you come?" in which you see if people use nach dtáinig or nár tháinig, and from that of couse you can know if they'd say go dtáinig or gur tháinig too.
Let's see:
Whole Munster (22 places) uses nár except 8 who uses ná (cad ina thaobh ná tháinís?... i don't know if they'd use go or gur), and for 6 we don't know.
Connachta: nár thá- in 19 places
nach dtá- in 20 places
nach thá- in 1 place
(in one place, both nach dtá- and nár thá- are given).
Ulster: na(ch) dtá- in whole Donegal (18 places) + Rathlin Island. Nár thá- in Tyrone and Co. Louth.
