What Does On Cloud Nine Mean?

Being on cloud nine means you are extremely happy. Often, this is the result of something good happening, not just because you’re in a good mood.
The phrase itself is an idiom, an expression that has a figurative meaning instead of a literal one —you are not actually on a cloud if you’re on cloud nine.
But where does the expression come from? As is often the case with old sayings, there’s no consensus on this. We’ll share a couple of explanations:
- It refers to a U.S. weather classification system used in the 1800s. In this system, there were 10 types of clouds. The cumulonimbus cloud, which is the tall and puffy cloud type many people find pretty, was the ninth type. In this theory, elation is like being on a high, on cloud nine came about to describe that.
- In Buddhism, the goal is for one to reach a stage of perfection called Enlightenment. This alternative theory suggests that Cloud Nine is a name for one of those stages.

- After we won the state championship, our team was on cloud nine for the rest of the year.
