No, you are wrong I'm afraid. What you're hearing as "should a key" is more than likely "sut dach chi". Every language has colloquial short forms, sigh. Unfortunately, even though I actually find conversations about linguistic differences really interesting I imagine there's no point continuing one with you. I tried to explain what I see the difference between dialect and accent being, but you just responded rudely and with another your rants about North Walians. Did one rub you up the wrong way or something? If you spoke the way you do on here I'm not surprised.
