Autocorrect / predictive text

[JJToner]

I'm attempting to enter text to a social media site, but my phone keeps 'correcting' my text. How can I stop it from doing this? I assume it's in a setting somewhere, but where? Thanks

I'm typing a link that includes amzn (for Amazon). My phone keeps correcting this to amen.

2 buttons over from the space bar on the stock Samsung keyboard is a multifunction button. If you long press this you can access the settings menu. Just shut off predictive text.
