Root Breakdown
Root-derived=nova
Short for Latin stella nova, 'new star' — nova is the feminine of novus (new). Early astronomers saw a star flare up where none had been seen and called it 'new.' The brightening doesn't create a new star; it's an old one suddenly visible, but the 'new star' name stuck. A supernova is the far more violent version.
