If you’ve been typing on your iPhone for a long time, odds are that you’ve made some mistakes in your typing, and the iPhone spell checking software has corrected them. Or, in my case — particularly because I work in the computer industry — the iPhone has “corrected” many of my acronymns the wrong way.

As a simple example, I like to use the acronym “DD” to refer to my devdaily website, but if I’m typing fast and not paying attention, the iPhone software keeps “correcting” that to “DE”. Well, “DE” isn’t right, but the iPhone has corrected this so many times when I wasn’t looking that it keeps defaulting to that behavior.

Since there are many similar acronym problems like this, I finally wondered, is there some way to reset my iPhone typing dictionary?

After digging around for the answer, I finally found it. On your iPhone — and presumably your iPad as well — you can reset your spelling dictionary by following these steps:

  • From the main screen, tap Settings
  • Then tap General
  • Scroll to the bottom of the list and tap Reset
  • Tap Reset Keyboard Dictionary

When you do this the iPhone brings up a window that says


“This will delete all custom words you have typed on the keyboard, returning the keyboard to factory defaults.”

If you’re sure this is what you want, go ahead and continue with the process, but if you’re not, just tap the Cancel button.

In my case I just did this recently, and I’m working on rebuilding my dictionary, a little more carefully this time.
