"I think that he will come"

Translation: Ninafikiri kwamba atakuja

[Stella_TheStar]

I wrote "Ninafikiri atakuja" and it was flagged as wrong. As a native Kiswahili speaker, I think the "kwamba" is optional

[_Abel_]

Agreed. Plus ninadhani would probably fit better since the meaning is more about thinking as in being unsure than the other uses of the word

[Bahatimoe]

Uko sahihi!!!

I wrote exactly what it said and was marked wrong
"Ninafikiri kwamba atakuja"
