Turpitude comes from Latin turpis, meaning "vile" or "base." The word is
often heard in the phrase "moral turpitude," an expression used in law to
designate an act or behavior that gravely violates the sentiment or
accepted standard of the community. A criminal offense that involves moral
turpitude is considered wrong or evil by moral standards, in addition to
being the violation of a statute.
