IPA: /ɪˈmjʊərənt/
KK: /ɪˈmjuːr.mənt/
The act of being confined or imprisoned, especially in a way that is permanent or for a long time.
The ancient practice of immurement was used as a form of punishment for serious crimes.
Immurement is formed from "in-" (meaning in or into) and "murus" (meaning wall in Latin). The word describes the act of being enclosed or trapped within a wall.
Think of being 'inside' ('in-') a 'wall' ('murus') — that's why immurement means being trapped within a wall.
