"Dad is eating bread."

Translation: Papa isst Brot.

[davidalleyne]

Wouldn't Vatti be more correct Vater is Father and Vatti is Dad or Daddy?

[emmmie]

I agree! Vater is more formal. I wrote Vati and was also marked wrong.

[tholenst2]

Vati (but not Vatti) should also be accepted.

[FrangoFranks]

They do mark Vati wrong though.
