The quality of being crude; lack of refinement, sophistication, or taste; or a crude, vulgar, or offensive remark or behavior.
From Latin 'cruditas' (rawness, indigestion), derived from 'crudus' (raw, uncooked); entered English through French influence in medieval times.
The Romans used 'cruditas' to describe indigestion from eating raw or uncooked food—over time it broadened to mean any kind of roughness or lack of refinement!
