I’m pretty much the last person to give pronunciation advice, but I hear “tyrd” as “tee-rr-d” in several songs I’ve heard. (“Meillionen” by Big Leaves/Elin Fflur comes to mind). I’m sure someone more qualified will come along to confirm/deny and help you with the rest.
Aran, I used bachen for boy and tended to just call my bitches ‘fach’, so: ‘bachen da’ or ‘Trikki fach dda’. I still say ‘fach dda!’ or ‘Toffi dda’ and use ‘paid’ a lot!! I say ‘come on’ rather than ‘let’s go’, but not in Cymraeg!! (I only know ‘dewch’ which is a bit formal!!) I never say ‘shall we?’!!! I’d use ‘nawr’ for now and I say ‘nawr te!’ so often that my dogs get up at the sound of it, knowing it means something is going to happen, like food!!
I’ve realised that I use “'ma nawr!” (from yma nawr) for ‘come here’, but if asked, my current 14 month toy poodle would say I make ‘nawr’ sound very fierce but she doesn’t take any notice as she knows I can’t make her come!!! My Cavaliers were much better behaved, save one who really was a bit lacking in a lot of ways, but brilliant at stalking, catching and killing!! (Not typical Cavalier activities!)
Little adjunct here, I met a lady whilst out with Soot this morning and she asked what was the language I spoke to him. She asked me if I was Welsh and I told her I was Anglo Welsh but trying to be bilingual. She asked me if I had a house in Wales ( we live in rural Cheshire), saying that she had a lovely house on Pen LLyn. Now, we’re the odd sort of people who just live in one house I could feel a bit of Meibion Glyndwr coming on but dragged it back by asking her to please say ‘bore da’ when she met people around her other house. One can but hope
I can so identify with your feelings of ‘Meibion Glyndwr’!! Having moved to N.Wales over five years ago and trying to learn the language since then, I somtimes find irritation welling up when I meet English people who live here that have made no effort to as least greet in Welsh or to pronounce place names!!
As to siarad efo fy gi, mae o deall ’ i fyny’ when I want him to jump in the car, he’ll come rushing down the stairs to ‘mae’na rhywbeth yn y cegin i chi’ and to praise him I use ‘mab da’!! - OK I know it means ‘good son’ but he is a very important member of my family!!
