There are other ways to say it in French, depending on the context and the level of formality:
* "Je t'adore" (pronounced "zhuh ta-dor") - This is a more passionate way to say "I love you."
* "Je t'aime beaucoup" (pronounced "zhuh tem bo-koo") - This means "I love you very much."
* "Je suis amoureux/amoureuse de toi" (pronounced "zhuh swee ah-moo-roo/ah-moo-rooz duh twah") - This means "I am in love with you."
It's important to note that in French, "I love you" is typically used more frequently and in a wider range of contexts than in English. So, while "Je t'aime" is the most common way to say "I love you," it can also be used to express affection or appreciation for friends and family.
