SSiW is one of the first methods I tried to learn this beautiful language. Dwi’n dechrau dysgu Cymraeg yn Mis Medi 2020. I started learning Welsh in Sept 2020. Since then, I have competed in Eisteddfod, wrote a song all in Welsh and was intereviewed by a few medias including BBC Radio Cymru (3 Aug 2021).
I love every minute of speaking this beautiful language and encourage everyone to try and keep going.
Why did I start learning and how does it help me? I invite you to read this post here on the SSiW forum. 
Why Did I Write a Song in Welsh?
