Hello TR7Ramen,
To help us get a better understanding of the issue, we’d like to ask a few questions.
1. When did this first begin? Were any changes made to your device or settings before this started? If so, what was changed?
2. Does this happen when typing in all apps, or only certain ones?
3. Are any text replacements set up on your device?
The above details will help us plan how to proceed.
We know you mentioned reviewing the settings, but please check out this link to ensure the settings are correctly configured for Auto-Correction and predictive text currently, so we can make sure there's no issue there.
This link will help guide you through reviewing those settings: How to use Auto-Correction and predictive text on your iPhone, iPad, or iPod touch
Use Auto-Correction
Auto-Correction uses your keyboard dictionary to spellcheck words as you type, automatically correcting misspelled words for you. To use it, just type in a text field.
To make sure that Auto-Correction is turned on:
1. Open the Settings app.
2. Tap General > Keyboard.
3. Turn on Auto-Correction. By default, Auto-Correction is on.
Thanks!
