Jewlery for jewellery/jewelry really irritates me. And anenemy for anemone. Pacific instead of specific. Yes, nucular is heard more and more these days. And what about people who drop vowels so you get Pleece for police, and such like. There's a man on the antiques programme who does that all the time. How much time does it actually save, if that's the idea, or is it just an affectation? And how often does one hear the letter D replaced by a J at the start of a word? As in jue for due etc. I consider that not as regional but just laziness. It's not uncommon to hear bockle for bottle in Manchester - neighbours of my granddaughters were heard to ask for "a lickle bockle" - so in a sense that could be seen as regional, but it's still laziness. Chimbley for chimney is a strange one too.
I know, I'm becoming a grumpy old woman aren't I?
