Shines or twinkles with small flashes of light, or the small bright lights themselves.
From Middle English 'sparklen,' possibly related to Old Norse 'spraka.' The word originally meant to scatter sparks, then evolved to describe any twinkling light.
Sparkles are created by light bouncing off irregular surfaces at different angles—it's why diamonds sparkle more than glass, and why snow on a sunny day creates such magical-looking fields of light!
