If you are having a hard time understanding someone this chapter is the best for you.
If someone will ask if you understand he will say:
Comprenez vous? (com pra nee voo) - "Do you understand?"
Your Reply:
Je comprends (Zhu comprah) - "I understand"
Je ne comprends pas (Zhu noh comprah pas) - "I don't understand"
Other things to remember:
Repetez sil vous plait (Re pe teh sil voo pleh) - "Repeat please"
Je sais (zhu seh) - "I know"
Je ne sais pas (zhu nu seh pah) - "I dont know"
Note: Do not be confused with Je suis meaning "I am" or Je ne suis pas meaning "I am not"
