Default [Q]Any way I can disable predictive text feature?

I want to disable predictive text(the one above my soft keyboard presenting me recent strings I have used) feature. But when I go to settings I cannot control whether to disable it!!

I cannot understand why amazon is forcing it. It is useless in my home language.The prediction is poor..

I googled for a while and all I've found is I cannot disable it in ordinary manner.

But my device is rooted so maybe... Is there any possibility that I can disable this annoying feature?

Please help if you know how!!

Thanks in advance
