How do I remove this odd field sometimes appearing when typing? I have recently started seeing an extra field middle left on the screen on my Android 5.1 Moto G 1st generation:

I cannot tap it. It also appears in other apps, for instance Hangouts. I first thought it was some sort of word suggestion, but it doesn't seem to change much or always appear.
Does anybody know what that is and how to remove it?
Oh, and what does &quot;winsomely&quot; mean..? Thank you.
It's not an extra field.  It's a malicious app that is causing it.  Download.StopBadApp Moble Security from playstore and scan the phone to detect and remove the malicious application.
