IPA: /ləˈbɒtəmaɪzd/
KK: /luh-bot-uh-mahyzd/
Describing someone who has undergone a surgical procedure that removes or damages parts of the brain, often resulting in a change in personality or behavior.
After the procedure, he seemed lobotomised, showing little emotion or interest in his surroundings.
Lobotomised → It is formed from "lobotomy" (from Greek "lobos" meaning lobe and "tomia" meaning cutting) and the suffix "-ised" (indicating the process of making or becoming). The word "lobotomised" refers to the process of having a lobe of the brain surgically cut or removed, typically to treat mental illness.
Think of 'cutting' ('tomia') a 'lobe' ('lobos') of the brain — that's why lobotomised means having undergone a surgical procedure that cuts part of the brain.
