A scintilla: the merest trace or hint or particle.
An absolutely minute amount.
It's the taste of the saffron in the paella
and the light of a single glow worm in a meadow.
It's the scent of a far-away lime tree; it's the shooting of a meteor.
The kindness in the eye of a frosty teacher (good luck with that one).
The sky-scribble of a butterfly in the corner of the eye.
Can you sense it?
Well, you're a bright spark, then, aren't you?
Nelson Creek glow worms.
Spot the frippet: scintilla. This word came to England in the 1600s. It's Latin for spark.
