Pictogram (象形), originally a stylized picture of clouds. The character was subsequently borrowed for a homophone meaning "say" and the original meaning came to be represented by 雲 through the addition of a semantic 雨 ("rain") component.
The simplified form adopted by the People's Republic of China in the 1950s eliminates this later addition and uses 云 for both "say" and "cloud".
