How to Get the Red Underline Off of a Word on Your iPhone

If your iPhone's dictionary does not contain a word you frequently use in your notes, emails or text messages, it will underline the word and suggest what it thinks is the correct word. This frequently happens when you use technical terms or Internet slang. You can't manually edit the iOS's internal dictionary, but you can use a workaround to make the device accept the word by creating a shortcut.

Step 1

Tap the "Settings" icon on the home screen to launch the Settings app, and then tap "General" to open the General Settings section.

Step 2

Tap "Keyboard" to view all settings related to the keyboard.

Step 3

Scroll down and tap "Add New Shortcut" to add a new keyboard shortcut.

Step 4

Type the word that gets underlined into the Phrase field, but don't type anything into the Shortcut field.

Step 5

Tap "Save" to save the shortcut. Your iPhone now doesn't underline the word automatically because it has been added to its internal dictionary.
