Ari in the video gives it fair go and it's good to see the warm welcome he gets in Glasgow.
He does get a couple of things wrong though and everybody is too polite to correct him because they know what he means. He refers to his kids as "quines and loons". That's something I'd associate more with the Doric dialect than Glasgow. "Boys and lassies" is what you'd say in Glasgow and the west.
He says "ken" a few times, something that's not used in Glasgow. "Ken" is what you'd say in place of "know" "Ye ken?" instead of "Y'know?" as an affirmation. Often people will add "ken?" to the end of almost every sentence in conversation. Again, it's something not in the Glaswegian dialect. I've identified what I call "the ken gap" in Greater Glasgow and (urban) Lanarkshire. You'll start to hear people say it in North Lanarkshire as you move further east. Places like Wishaw (Wishy), Carfin, Newarthill and all points east of there. Ken comes back into the dialect as you go south west of Glasgow again. It's part of the dialect in rural east Ayrshire in places like Stewarton, Dunlop and Kilwinning.
