Wait, you're saying Dywyddyr is a real word?Dywyddyr:
being a Welsh(-ish) word it's not as as easy as DEE-wih-DEAR.
The y is pronounced as an i, the w as u (oo), d is fricative (closer to t) and dd is th.
So it's tioo (like Tiw the Norse god - Tuesday, not quite chew) ith ir.
Tiu-ith-ir.
Keep practising.
I figured you'd just typed a bunch of random letters as your user name. I've been mentally pronouncing it as just "D" and ignoring the apparently random assortment of letters that follow it.
What does Dywyddyr mean?
