If you’ve been using your iPhone, iPad, or iPod touch for a while, you’ve probably had an “autocorrect moment” where your device repeatedly insists on mistakenly “correcting” something you’re trying to type into some other obscure word. Most often this is the result of the device learning a word from past usage, and while iOS doesn’t offer any way to directly edit the autocorrect dictionary, there are a couple of ways to deal with this problem. If you’re dealing with only one or two words that iOS is always getting wrong, you can override the autocorrect feature by defining keyboard shortcuts set to the correct word. To do this, simply go into your Settings app, select General, Keyboard and then scroll down to the “Shorcuts” section and use the “Add New Shortcut” button to create a new entry with the word that you do not want autocorrected. This also works to override the built-in autocorrect dictionary for less common words that you may find yourself using often but that your iPhone hasn’t yet learned properly.
On the other hand, if your autocorrect situation is a complete mess, you can simply reset the entire keyboard dictionary by choosing the “Reset Keyboard Dictionary” option found under General, Reset in the iOS Settings app. This will erase all of the learned autocorrect entries from your device, effectively allowing you to start from scratch.
