* Je t'aime: This is the most common and straightforward way to say "I love you" in French. It is used for close friends, family, and romantic partners.
Informal:
* Je t'adore: This is a more passionate and intense way to say "I love you" and is typically used in romantic contexts.
* Je t'aime beaucoup: This means "I love you very much" and is a more affectionate way to say "I love you."
Very informal:
* J't'aime: This is a shortened version of "Je t'aime" and is only used with close friends and family.
Note:
* "Tu" is used for familiar second-person singular, while "vous" is used for formal second-person singular or plural.
* The pronoun "t'" is a contraction of "te" and is used when the verb ends in a vowel.
