What type of cloud that is curled would have the root word?

The type of cloud characterized by a curled appearance is called "cirrus." The root Word "cirr-" comes from the Latin term "cirrus," meaning "curl" or "tendril," which describes the thin, wispy, and often curly shape of these high-altitude clouds. Cirrus clouds are typically found at altitudes above 20,000 feet and are composed of ice crystals.
