Formal:
* Rwy'n dy garu di: This is the most formal and literal translation, meaning "I love you." It is often used in written contexts or when addressing someone you are not close to.
Informal:
* Dw i'n dy garu di: This is a more casual version of the above, often used in spoken Welsh. It can be translated as "I love you" or "I love ya."
* Caru di: This is a very informal way of saying "I love you," often used between close friends or family. It literally translates to "love you."
Other options:
* Mae gen i gariad mawr i ti: This translates to "I have great love for you," which is a more poetic way of expressing love.
* Rwy'n hoff iawn ohonot: This means "I am very fond of you." It is a less intense expression of love, but still conveys strong feelings.
The best way to say "I love you" in Welsh depends on your relationship with the person you are talking to and the situation.
