Welche Sprachen sprechen Sie? (Deutsch/German)

¿Qué idiomas habla usted? (Español/Spanish)

Quelle langue parlez-vous? (Français/French)

EDIT: These sentences are now up to date.

  • English and Turkish as native languages, I’ve also studied French as a prep-year for highschool so I can understand it but don’t speak it fluently, same with Italian, somehow. Other than that I’ve been learning Mandarin for a year and I’ll take the HSK 3 exam in a few months :D
