Etymology
Origin of cloudy
First recorded before 900; Middle English cloudi, Old English clūdig “rocky, hilly”; cloud, -y 1
Explanation
When the sky is cloudy, it's so full of clouds that you can't see the sun. A cloudy day isn't ideal for a trip to the beach, and a cloudy night isn't great for star gazing. A cloudy sky tells you that rain's on the way, while a cloudy pond or a cloudy glass of water isn't translucent — you can't see through it. You can also describe an issue, thought, or memory as cloudy when it's vague or half-remembered or unclear. Cloudy comes from the Old English word clud, "mass of rock," and later "cloud," based on the way a cloud can resemble a rock or hill.
