Adding words to your iPhone’s dictionary is a breeze with iOS 17. Whether you’re tired of autocorrect changing your perfectly good words or you want to save time typing out long, complicated terms, customizing your iPhone’s dictionary is a handy skill to have.

iOS 17: How to Add Words to Dictionary on iPhone

Before we dive into the steps, let’s talk about why you might want to add words to your iPhone’s dictionary. Maybe you use technical jargon for work, or you’ve got a unique nickname that keeps getting “corrected” to something entirely different. By adding these words to your dictionary, you’ll make typing on your iPhone a smoother, less frustrating experience.

Step 1: Type the Word in Any App

Type the word you want to add to your dictionary in any app that allows text input.

When you type a word that’s not recognized by your iPhone, it’ll be underlined in red. Don’t let that scare you off; you’re on the right track.

Step 2: Tap the Word

Tap the underlined word to select it.

A menu will appear with several options, like Cut, Copy, and Replace. You might also see a suggestion for the correct spelling—if your iPhone thinks you’ve made a mistake.

Step 3: Choose “Learn Spelling”

From the menu that appears, choose “Learn Spelling.”

After you select “Learn Spelling,” your iPhone will add the word to its dictionary, and it will no longer autocorrect it to something else. This means you can type your specialty words without having to fight with autocorrect every time.

After you complete these steps, your iPhone will remember the new word and won’t try to autocorrect it in the future. This small change can save you a lot of time and frustration, especially if you often use words that aren’t in the standard dictionary.

Tips for Adding Words to Dictionary on iPhone

  • If a word keeps getting corrected, add it to the dictionary to save yourself the hassle.
  • You can add names, places, and even slang terms to your iPhone’s dictionary.
  • If you accidentally add a misspelled word, you can reset your dictionary in the Settings app.
  • Use this feature for words you type often to save time on editing and correcting.
  • Remember that this won’t affect predictive text suggestions, only autocorrect.

Frequently Asked Questions

What if the word doesn’t have a red underline?

If the word you’re trying to add isn’t underlined in red, your iPhone might already recognize it, or it might be part of a recent update to the iOS dictionary.

Can I add phrases or only single words?

At the moment, you can only add single words to the iPhone’s dictionary. If you often use a specific phrase, you may still have to type it out each time.

How do I reset my dictionary if I make a mistake?

To reset your dictionary, go to the Settings app, tap General, then tap Reset, and select “Reset Keyboard Dictionary.” Be careful though; this will remove all the words you’ve added.

Will adding words to my dictionary affect all my devices?

If you’re using iCloud, any words you add to your dictionary will sync across all your Apple devices, saving you time and ensuring a consistent typing experience.

Can I remove a word from the dictionary after adding it?

Yes, you can remove words by resetting your dictionary in the Settings app. However, you can’t remove individual words; it’s an all-or-nothing reset.
