It's a very strong expression of affection, but it's not necessarily romantic love. It can be used for family, friends, and even pets.
Here's a breakdown of the phrase:
* Ti: This is the informal "you" in Italian.
* voglio: This means "I want" or "I love".
* molto: This means "very" or "much".
* bene: This means "well" or "good".
So, "ti voglio molto bene" translates to "I love you very well". It emphasizes a strong and deep love or affection.
