I have to write the sentence "You (plural) need to make up your own mind" in french using "il faut que" and "prendre tes propres decisions." Would the result be "Il faut que vous prenniez tes propres decisions"?

Answer 1

Close with one error in the verb. The Present Subjunctive stem is found by dropping the -ant of the Present Participle. prendre = prenant (note only one "n")
Il faut que vous preniez vos propres décisions. Because you chose to use "vous" as the subject, don't forget that the possessive adjective will then be vos. Now, if you had followed the model and used tu = Il faut que tu prennes tes propres décisions. (you would have had the double "n" and kept "tes.")

Sra (aka Mme)
