Etymology: Mollisols get their name from Latin. "Mollis" means "soft," and it describes the loose, crumbly, easily worked topsoil that makes these soils so productive. The second half, "-sol," comes from Latin "solum," meaning ground or soil, and it is a standard ending for the names of soil orders in the USDA's soil classification system. Soil scientists built the name from parts of older words to fit a single, consistent naming scheme. The other orders follow the same pattern, such as Alfisol and Spodosol, so the name signals the soil's character to anyone who knows the system.
