If you learn swahili and translate directly from English you will be making many mistake just like many of the educated swahili people take english phrases and translate them direct to swahili. kitabu ni kizuri; can be correct or wrong it depends.If were somewhere together and I gave you a book.You read it a little or the back cover and say "Kitabu ni kizuli" I will understand you.But by just saying "kitabu ni kizuri" I wont understand which book are you referring to.
