1.^ angreji mein "dooradarshan" ko "telivijhn" (television) kaha jaata hai. pratha ke anusaar "jh" ko kabhi-kabhi "za" likh diya jaata hai jis se yeh shabd "telivijn" likh diya jaata hai haalaanki yeh poora sahi naheen hai. "telivijhn" shabd ko sahi bolne ke liye jh ke uchchaaran par dhyaan dein kyonki yeh "za" aur "jh" donon ke uchchaaran se bhinn hai.
