For the dialects of English spoken in Scotland, see Scottish English.
For the Germanic language which diverged from standard Middle English, see Scots language.
I think they were talking about Scottish English, not Scots.
There's also Scottish Gaelic, which seems to be often confused with Scots and Scottish English.
Then again, I'm not from Scotland and have never been near there, I'm just getting this from Wikipedia and from a few YouTube videos I watched some months/years ago.
My wife and I were on a flight once, we had been in Canada on a previous trip where they do French and English for every message.
We were sitting on this plane trying to work out what language the pilot was speaking, when we finally worked it out. No idea what the message was but we're pretty sure it was an Australian captain speaking what they refer to as "English".
