Here you go, know your en- and your -en
Prefix: en- “…forming verbs”
Suffix: -en “makes the word a verb”
Put them together and you’ve got enbrighten:
The only similar I can think of is enliven, which, of course, is a synonym of liven.
(Srs. suggestion: Why not Enbright instead? )
All right, GE, keep on enbrightening our world…
