"They adore French"
Let's break it down:
* Tes is the plural possessive pronoun "your" in French. However, in this context, it's likely a mistake. It should be "Ils" or "Elles" which means "They" (masculine or feminine plural).
* adorent is the third-person plural present tense form of the verb "adorer," which means "to adore."
* le français is the definite article "the" followed by the noun "French."
Therefore, the corrected phrase would be "Ils adorent le français" or "Elles adorent le français", meaning "They adore French."
