IPA: /ɪnˈtʃeɪnmənt/
KK: /ɪnˈtʃeɪnmənt/
The action or condition of being linked or bound together, often in a restrictive way.
The enchainment of the prisoners was a grim reminder of their captivity.
Enchainment → It is formed from "en-" (meaning to cause to be in) and "chain" (from Old French *chaîne*, meaning a series of linked elements). The word "enchainment" refers to the act of causing something to be linked or bound in chains.
Think of being 'caused to be in' ('en-') a 'series of linked elements' ('chain') — that's why enchainment means being bound together.
