Origin: The origin of the idiom “on cloud nine” is somewhat unclear, but it became popular in the mid-20th century. One theory suggests it comes from the U.S. Weather Bureau’s classification of clouds, where cloud nine was one of the highest and fluffiest types of clouds (cumulonimbus). Another theory links it to the mystical significance of the number nine in various cultures and traditions, symbolizing perfection and happiness. Regardless of its exact origin, the phrase effectively conveys a state of extreme happiness, as if one is floating high above the ground on a cloud.
