retarded

The word "retarded" originates from the Latin verb retardare, meaning "to make slow, delay, or hinder," which itself is a compound of the prefix re- ("back") and the adjective tardus ("slow"). This literal sense of being "held back" or "made slow" entered English in the late 15th century as a verb. By the late 18th century, its participial adjective form began to be used in scientific and medical contexts to describe delayed development or progress. Over time, its primary application shifted to describe intellectual disability, a usage now considered offensive and outdated in medical and social contexts, having been largely replaced by more precise and respectful terminology.
