How did altostratus cloud get its name?

Altostratus clouds derive their name from Latin, where "alto" means "high" and "stratus" refers to a layered or flat appearance. These clouds typically form at mid-level altitudes, between 6,500 and 23,000 feet, and often appear as a gray or blue-gray layer that can cover the sky. The name reflects both their altitude and their characteristic flat, uniform appearance.
