Is there a way to turn off auto-correct?
When "tonight's supper" becomes "Tonoght's suppee", it's time to go.
Yes, you can turn that off. Go into Settings > Language & Input > Select the Gear symbol next to your Keyboard type (mine is the Android Keyboard (AOSP)> Select Auto Correction > Then whatever option you want: Off, Modest, Aggressive, etc. That should do it.
