verb / noun

twinkle

TWIN-kuhl/ˈtwɪŋkl/

A brief, lively sparkle.

The star gives a brief twinkle against the darker sky.

A three-moment sequence of the same star in a small constellation, changing from faint to bright to faint; the surrounding stars stay unchanged, making the brief flash visible.
Etymology

The pieces suggest repeated blinking: light appears and disappears like an eye rapidly opening and closing. The Old English verb already covered both winking and shining with intermittent light.
