IPA: /dɪsˈeɪblmənt/
KK: /dɪsˈeɪblmənt/
The act of making someone or something unable to function or operate normally.
The disablement of the machine was necessary for safety reasons.
Disablement is formed from "dis-" (meaning apart or away) and "able" (from Latin "habilis", meaning able or capable) and "-ment" (a suffix used to form nouns indicating an action or resulting state). The word refers to the state of being unable or rendered incapable of performing certain activities.
Think of 'dis-' meaning apart and 'able' meaning capable — disablement refers to the state of being made incapable.
