A slowing down or delay in progress, development, or movement; in scientific contexts, refers to deceleration or impedance.
From Latin 'retardare' meaning to make slow, from 're-' (back) and 'tardus' (slow). Originally a neutral scientific term, it became problematic when applied to intellectual disabilities in the 20th century, leading to its replacement with more respectful terminology.
This word perfectly illustrates how scientific terminology can become social stigma - what began as a neutral descriptor for delayed development became a slur, forcing the scientific community to continuously adopt new terms. The euphemism treadmill shows how language and social attitudes dance together in complex ways.
This term's clinical use in developmental psychology became weaponized as a slur against women and girls, particularly those with intellectual disabilities. Its use conflated developmental delay with feminine weakness, reflecting mid-20th century ableist and sexist assumptions.
Use precise clinical terminology: 'developmental delay,' 'intellectual disability,' or specific diagnostic criteria. Avoid retardation entirely in contemporary contexts.
