Retardedness

/rɪˈtɑːrdɪdnəs/

nounC2

Definition

Retardedness is the condition of having slower development, especially in mental or physical abilities. It describes when someone's growth or progress happens more slowly than usual. However, this word is old-fashioned and can hurt people, so it is better to use respectful terms like "developmental delay" or "intellectual disability."

Make It Stick

  • Think of "retardedness" like "slow," but about growth or development over time, not just speed of movement
  • Picture a plant growing slower than others in the garden—it takes more time to reach the same size
  • It’s the feeling when someone struggles to learn or do things as fast as others, needing extra help
  • Sounds like "re-TARD-ed-ness" → imagine a clock that runs late or slow, making everything happen later than normal
  • In stories or history, this word was used long ago to describe people with learning difficulties, but now we use kinder words
  • NOT like "slow" (which can mean moving slowly now), retardedness is about overall development being delayed
  • NOT like "disability" (broader term), retardedness focuses on delay or slowness in growth or ability
  • NOT like "delay" (temporary slow), retardedness can be a lasting condition
