Definition of cretin

The word "cretin" has a complex and controversial etymology. The term originally referred to a type of congenital disability caused by cretinism, a condition now known as hypothyroidism. Cretinism is a result of iodine deficiency during fetal development, leading to physical and intellectual disabilities. The word "cretin" comes from the Old French "crétin," which was derived from the medieval Latin "xriðinus," meaning "low-born" or "villain." This term was later linked to the Greek word "krettes," meaning "idiot" or "simpleton." In the 17th and 18th centuries, the term "cretin" was commonly used to describe individuals with intellectual disabilities, including those with Down syndrome. However, its usage was gradually phased out due to its pejorative connotations and scientific inaccuracy. Today, the term "cretin" is considered offensive and is no longer used as a medical or clinical term.
