How to delete / remove languages under Personal Dictionary

A

AC Question

When I navigate to Personal Dictionary (Settings > Advance Settings > Language & Input > Personal Dictionary, I had few languages listed here which I think is redundant and I would like to delete / remove them. But I can't find a way to do it. Any help pls?

The list goes like this:
All Language >
English (Country A) >
English (Country B) >
Chinese (Country C) >

Note: I am not asking how to delete a personalized or self-added words. I wanted the whole Language tab(s) to be removed. Thank you very much. :D
