Default Re: [Dixonary] Let Voting Begin: Round 3063 Optriculum

I'll try 7 and 9 (though I'm a bit suspicious of the use of "penumbra" in

>> 7. The penumbra of a visible electrical discharge, such as St. Elmo's Fire


>> 9. An early form of color TV in which successive fields are scanned in three primary colors
