I know this thread is outdated but hey
The Scottish Government considers Lallands (central) and Doric (North-East) to be regional languages, and they are even considering putting up to 60 Scoats speakers into classrooms to help encourage the use of Scoats.
I personally think it's a dialect now, in the past definitely a language, but you only really see Glaswegians, and some Aberdonians with the strong proper accents and who use proper scots words rather than english words. I come from quite a Scots speaking area, but people here classify it as "ned speak" or "slang" something undeseriable. I think this is a common attitude in Scotland that needs to change.
I welcome the Scottish Governments attempts to bring Scots into the media, classroom and even into exam papers but unless they start teaching it without heavy influence from english, it's going to continue to become closer and closer to English. I think as well the decline of Scottish words is due to the fact many parents teach their children that "cannae, dinnae, wulnae, huvnae" are unacceptable and you must say "cannot, do not etc".
Anyhoo, a'v goat tae go fur the messages noo
