I hesitate to type this, given the number of deletions. I didn't see the original comments, but it's also a perfectly benign word in Doric Scots. I have seen it causing consternation in the central belt of Scotland, however, since it's frequently misunderstood. (My late husband spoke Doric.). The meaning in the central belt is slightly different, but nothing like the meaning in Standard English.
I've actually seen it inscribed on a long-service medal, given as part of a retirement gift in the late '90s.
The various Scots dictionaries available online have a plethora of examples.
The Doric is dying out, but I'd say that it's a term that is still well used by Aberdeenshire folk over the age of 40.
Anyway, back on topic.
It's certainly the case that in the heady days after IndyRef many more independent supporters joined the SNP. Since then, numbers have plummeted - and that happened while NS was leader of the party: to my mind, that was a clear rejection of her leadership. I can't find the current figures, but she lost more than 50,000 members between 2018 and 2023. The party lost around another 15 thousand by the end of '24.
People have been well aware of the failure to keep proper account of party funds. I'd say that there's been disillusionment around that, the shame of violent men being allowed into the women's prison estate and the farce of the party seeming to sit back in spite of the promise that Scotland would not be dragged out of the EU against its will.
Had Murrell's trial gone ahead sooner rather than later, I think that we'd be looking at lower numbers of SNP MSPs in parliament today. I don't know how the party is going to come back from this.
