We are being too informal -
in six different languages, in fact!
Each of these clues contains a second-person pronoun in some language; it needs to be changed to the formal version of that pronoun. (So French "tu" becomes "vous"; Spanish "tú" becomes "usted"...)
Additionally, each clue also has a second-person conjugation of the word for "to be" in that language - we need to change that to the formal form as well.
The full list is:
[Italian: "tu sei" → "Lei è"]
→ Leia's father
[Spanish: "tú eres" → "usted es"]
They jotú in cheress
→ They jousted in chess
[German: "Du bist" → "Sie sind"]
Duge where some were Bistarin
→ Siege where some were Sindarin
[Czech: "ty jsi" → "vy jste"]
