Yesung mean Art like voice 

Yesung’s real name is Kim Jong Woon (김종운). His hanja name is 金鐘雲. Now when you translate the 운 (un) partfrom

his hanja name (雲), it will mean 'cloud'. And that’s how fan gave him nickname as ‘cloud’ or usually they call him ‘cloud

prince” or구름 왕자 ♥

Sometimes fans also shorten 구름 as 굶. Itstillsounds the same. Like how 엘프 (ELF) gets shortened as 엞. They also still

sound the same :)

Now, a bit out of topic but maybe interesting forsome of you, especially Yesung’s fans^^
