How do I reset my predictive text? It no longer reverts back to my word with backspace

[Ade Stocker]

Initally my S6 brilliantly reverted back to my original word with one touch of backspace but now it's behaving like an iphone and does what it wants.

I don't know what I did to change it.

Any help is greatly appreciated.

thanks
