How to remove contacts from LG Keyboard dictionary

A

AC Question

i have a bunch of nonsense contacts like a4564tydyrt6756rfghf67r8566567fuy56785@kijiji.com, and others from craigslist and such from buy/sell...

Now, my phone likes to use these overly long email addresses when I am swyping, and then it takes me 10 seconds to backspace them.. And ontop of that, I'm mute so I use TTS to speak so this is even more of an annoyance.

If i clear my suggestions, i presume they will simply return, as they are google contacts.. I could go deleting contacts, but they are pretty hard to find because they are just random letters.. I can't long-tap to delete the suggestion either..

Any advice?
