Yakamoz
Etymology
From Turkish, borrowed from Greek. It names the glint of moonlight on water and can also refer to the phosphorescent glow of marine plankton at night. In 2007 it was voted one of the most beautiful words in a large international survey, which boosted its fame abroad.
noun · /YAH-kah-moz/
The reflection or shimmer of light — especially moonlight — on water.
What it names
That silvery glimmer thrown across the surface of the sea or a lake by the moon, and the play of light dancing on the ripples.
Example
We swam out at midnight, the yakamoz breaking into silver flecks around our arms.
Related idea
Swedish mångata names the same kind of glimmer but pictures it specifically as a road of moonlight; yakamoz is broader, covering shimmer and even sea-sparkle from living organisms.
