Oh dear! I always thought those SNP guys were a dodgy lot.
They want to blame their spell checker, but clearly someone wasn’t paying attention!
I do wonder, though, whether the creeping americanisation of English is being accelerated by the careless use of software originating in the States. I constantly find that MS Word wants to correct my English English. As far as I know I have set all the settings for English English.
What’s worse is there is no sign of a setting for Scottish English!
(Ed. – What?)
