latin right
'Left' in Latin is 'Sinister' and 'Right' is 'Dexter'
It's derived from the English words copy and right; in the most basic sense, it is the right to copy.
Copy is from the Latin copia, an abundance (as in copious), and right is from the Latin rectus.

Aether is the right answer; Latin for aether is aether!
