IPA: /dɪˈfiːtɪzəm/
KK: /dɪˈfitɪzəm/
A way of thinking where a person believes that failure is inevitable and does not try to change the situation.
His defeatism prevented him from taking any action to improve his circumstances.
Defeatism is formed from "defeat" (from Old French *defaite*, meaning failure or loss) and "-ism" (a suffix used to denote a practice or philosophy). The word refers to a belief or attitude that accepts defeat as inevitable or promotes a sense of resignation to failure.
Think of 'defeat' as a failure and '-ism' as a belief system — defeatism is the belief that failure is unavoidable.
