iPhone keyboard’s Auto-Correction feature is time-saver and great help for people who are not used to touch typing. iPhone suggests word as you type when the word is not in the keyboard dictionary. You tap the “X” next to a suggested word to reject the correction, and iPhone will add your word into the keyboard dictionary. Your word will then not show up for correction again.
In due course, you have high probability of messing up the keyboard dictionary. For example if you spell “dont” without an apostrophe and reject the suggested correction for a few times, iPhone keyboard will add “dont” into the keyboard dictionary and will not suggest correction for you subsequently.
To erase all the words you added to the keyboard dictionary:
**Settings > General > Reset > Reset Keyboard Dictionary**

Select “Reset Dictionary” to clear your words and reset the keyboard dictionary to factory default.
