How do I say I love you very much in Welsh?

Dw i'n iawn caru chi

Pronunciation:

Doo-een Ee-ah-oon Kar-ee Kee

Remember to roll your R's and the 'ch' is pronounced as a 'K' in English but from the back of your throat. (if that doesnt make sense, you can just substitute 'chi' for 'ti' (pronounced: Tee), it means the same thing but is more informal

:) cheers mate
