Formal:
* Eu amo você: This is the most formal and literal translation, suitable for formal situations or when addressing someone you don't know well.
Informal:
* Eu te amo: This is the most common way to say "I love you" in a romantic context, especially among friends and family. It's considered more intimate than the formal "eu amo você."
* Amo você: This is a shorter and more casual version of "eu amo você," often used among close friends and family.
* Eu te adoro: This translates to "I adore you" and is used for expressing deep affection and love, often for someone you have a very close relationship with.
Other Options:
* Eu gosto muito de você: This means "I like you very much" and is a softer way to express affection without explicitly saying "I love you."
* Eu amo-te: This is the archaic form of "eu te amo" and is still used in some regions of Portugal.
The best option will depend on your relationship with the person you are speaking to and the context of the conversation.
