Having friends who are both Scottish & Welsh I would say that the written word should follow the pronunciation. I say house - my Scottish colleague says hoose. I know what she means and would expect the written text to reflect that. Welsh is much trickier - they use their own Welsh words that bear little resemblance to the English. Again it’s only by knowing what they mean that you can get the true picture. My lovely Welsh sister-in-law will often ask for a cootch. Yeah! I was a bit shocked too till I discovered it was cwtch (God I hope I spelled that right) and just means a hug or cuddle! I’d rather people used language correctly. I don’t need or want spoon fed some Anglicised version of what was said. Authenticity please!

I'm Scottish, I may not be in the majority, I'm not sure as I'm not on Facebook or any other social media, but when I am commenting on something on MN or similar I use proper English. In this context how each commenter pronounces words is irrelevant and therefore I think people should write clearly and concisely so everyone understands. I also think it important to use proper grammar (although I'm completely uneducated so may get it wrong sometimes).
However, if I'm texting/messaging a friend I sometimes use Scottish pronunciations. I also enjoy it in literature. So I agree there is a time and place for this

Blimey this is risky. Not a writer but I am Irish and I don't think my accent goes against the rules of pronouciation! 🤷‍♀️

Like, bate instead of beat, is that an accent or a variation in parts of Dublin. Because cheat isn't chate. Seat isn't sate.

Also, do English people ever do this intentionally?
Eg, I have seen supprise not surprise. A specifically English mistake. And "lore and order" (law and order). But I don't think this sort of thing is ever deliberate!

Some of the Scottish spellings might be mistakes??

Another mistake I would see only from a bearer of a certain accent is when a word ends in a uh sound but the writer puts an er on the end. The only example i can think of is Francesker 🤣

@CoalTit
A bit late to this conversation, but just to add that the words 'bate' or 'auld' would convey to me (as an Irish person) different shades of meaning than would 'beat' or 'old'. Or more precisely, using those non-standard spellings would convey information on the writer's mood or intent..which may be humorous or irreverent.

As for eejit rather than idiot - the word is used a lot in Ireland (idiot is used less) and though eejit is derived from idiot the pronunciation is quite different. Again there's a slight disparity in meaning - eejit isn't as harsh maybe, at least where I'm from. I consider them separate words at this stage.

I can't comment on the Scottish words you mentioned.

I don't think that the Irish writers, at least, are trying to show you how to pronounce the words in their accent.

They're just trying to pinpoint their meaning to those of us who use 'bate' as well as 'beat' , 'auld' as well as 'old', and 'idiot' and 'eejit' in speech.

I'm Scottish but also speak Dutch. How is the Scottish pronunciation of "house" more phonetic and logical than the English (notwithstanding that several northern English dialects also use the "oo" sound? I find the OP sound easier to read if represented by the Swedish or Norwegian characters anyway, which some Shetland dialect speakers write. The "oo" sound is much more common in Scandinavian languages and often moderates the letter in front of it (eg where a "sk" or "sj" precedes it, the prounucuation changes to a "sh" or 'wh" sound).

The "ou" sound is simply standard northern Germanic pronunciation. The Dutch word is "huis" and is pronounced in the same way. The "oo" sound seems based either on retention of an older form of English or Norse pronunciation following the former Danelaw areas.

Neither is more or less logical. Different dialects within a language are common but would only become more logical if the dividing line between dialect and a whole different language were present.
