What does it mean...Je te deteste.

Why is the te there? Another one is je t'adore?

je t'adore means I love you. When you put the "te" in there that refers to the person you are talking to.

Je te destese means I detest you (I do no like you)

Good job, both of you! I do NOT like you, is the English of Je te déteste. Another way to say that is "Tu ne me plaís pas." = You are not pleasing to me; ergo: I do not like you!

Mme

actually, je t'aime means i love you, not je t'adore because its illogical, i take AP French

The word "te" in "Je te déteste" and "Je t'adore" is called a reflexive pronoun. In French, reflexive pronouns are used when the subject of the sentence is also the object of the action.

In the sentence "Je te déteste," the subject "je" (which means "I") is performing the action of "déteste" (which means "hate") onto the object "te" (which means "you"). So, the sentence translates to "I hate you."

Similarly, in the sentence "Je t'adore," the subject "je" is performing the action of "adore" (which means "adore") onto the object "t'" (which means "you"). So, the sentence translates to "I adore you."

To understand how reflexive pronouns work in French, you need to know the different forms they take depending on the subject. In this case, "te" is used when the subject is "je" (I) and the object is "you." Other forms of reflexive pronouns in French include "me" (myself), "se" (himself/herself), "nous" (ourselves), and "vous" (yourselves/each other), among others.
