There are some cultures in which in everyday conversation, different languages can be used within the same sentence. For example there are some who might type in Spanish and English at the same time, while there are others who might also type in Chinese and English, Japanese and English, Korean and English, and so on.
Now if you are a multilingual speaker, you know that sometimes the autocorrect feature on iOS can be pretty annoying because it usually attempts to correct the other language. The good news is that with iOS 10, Apple is making it so that when you do type multilingual sentences, it will be able to detect it and won’t try to autocorrect your words.
How this works is pretty simple. As you can see in the screenshot above, this is similar to adding a new dictionary/keyboard to your current setup. There are several language combos that iOS 10 recognizes at the moment, like Spanish-English, Italian-English, Korean-English, Japanese-English, and so on.
Once you have chosen your desired language combo, from there on typing in multiple languages should not be an issue anymore. iOS 10 is currently in its first beta and is planned for a release later this year.
