I hope someone is still going to see a post on an old thread.
I'm an author wanting to confirm colloquial usage in Welsh for the phrase "I love you" as said by a man (from the South) to a woman. Is "Rwy'n dy gari di" the only correct way to say this? I also keep seeing "Cara 'ch" (or "Caru 'ch") My characters are both young, so I need something that really sounds more modern. Can either phrase be used? Is Cara 'ch just more casual?
