Yakamoz was declared as the most beautiful word in the world by a competition entitled “The most beautiful ABC of the world" ("Das schönste ABC der Welt”) in Berlin, Germany. Yakamoz is commonly referred to as the reflection of the moon as it shines upon the water.
Though its original meaning is now nearly forgotten, a yakamoz is actually the light coming from the ocean or salt-water rivers that is caused by microorganisms Noctiluca scintillans, commonly known as the Sea Sparkle, and considered as the fireflies of the sea. When these creatures are moved or disturbed, they create a wonderful luminescent effect that, when gazed from afar, look like a scene in which moonlight shines in the sea.
The closest English equivalent to yakamoz, they say, is phosphorescence.
