The Chinese word 乌云 (wūyún) for "dark clouds" is composed of two characters: 乌 (wū) and 云 (yún). The character 乌 originally meant "crow" and was used to describe something black or dark. Over time, it came to be used more broadly to refer to anything dark or cloudy. The character 云 originally meant "cloud" and was used to describe the white, fluffy clouds that we see in the sky. However, it can also be used to refer to dark clouds or even storms. When these two characters are combined, they create the word 乌云, which specifically refers to dark clouds that are often associated with rain or storms.
