S'mae pawb!
Today we're are learning the different ways 'si' can be used in Cymraeg. It's mainly a sound used to replicate loanwords when the sound or letter loaning in doesn't occur in the language.
This is a bit of a vocab dump and I know it's a long video for a bit of a simple rule, but I was mainly hoping to give you lots of words that aren't on the 625 list so I'm not repeating things.
Mwynha! / Joia! / Enjoy!
