How to disable personalised text predictions?

[SAVVYSCLUTTER]

I'd like to stop my phone from remembering words I type and suggesting them later, without disabling predictive text entirely or using another keyboard app.

I know I can click 'Erase personalised predictions' but don't want to keep doing this.

The Samsung Keypad is geared up to do this to help with typing so I'm not sure you can adjust the settings to allow what you want to do @SAVVYSCLUTTER 

You could turn off Enhanced Accuracy if it's turned On in the Keyboard settings. 

Also 3rd party keyboards may also have this built in to their code.
