Lmao! It is easier than you think! Phonetically you say - Gwas-an-aaaeth Am - dy(smaller y)ifynn-n-wyr (dyfinywr) Cy-hoedd-us. If that doesn't help, you can try saying "Gwas-anaeth Amiddi-fynn-wyr - cy-hoedd-us". If you put the Welsh into Google translate you can hear the pronunciation. We have even worse words lmao but living here all my life I know a good bit of Welsh and how to say things here. :)
