How to remove the languages on the keyboard from the phone?

I need help. If I want to change the language on my mobile keyboard, it says: German, German (CH), Έλληνικά, English (Uk), English (Uk) / English.

And I do not want to have that anymore. I still do not know how to remove the other languages.

Have a: Huawei Y6 2 Compact

I think that's an Android. On my Samsung Galaxy Tab, this is how it works:

settings

General Administration

language

language and input

Virtual keyboard

Samsung keyboard (would be more like "Huawai" with you)

Manage input languages

Deselect unwanted languages from the list of activated languages.

However, if the Huawei have put their own derivative on pure Android, it can look very different.

But why do you want to do that? You do not have to use it.
