retarded

word

/ɹiˈtɑɹdəd/
ri-TAR-did
/ɹɪtˈɑːdɪd/
ri-TAR-did

Definition

This word was once used in medical or technical contexts to describe delayed mental or physical development, but in modern everyday English it is usually offensive when used about a person. In some technical contexts, it can still mean slowed, delayed, or reduced.

Usage & Nuances

Strong caution: avoid using this for people in modern English, because it is widely heard as a slur. Safer alternatives depend on context: 'intellectual disability', 'developmental delay', 'slow', 'delayed', or 'slowed'. In technical collocations such as 'flame-retardant' or older phrases like 'retarded growth', the meaning is about slowing or delaying, not insulting someone.
