IPA: /dɪˈfɔːltə/
KK: /dɪˈfɔltər/
A person who does not meet their responsibilities or fails to do something they are required to do, especially in legal or financial matters.
The bank took legal action against the defaulter for not repaying the loan.
Defaulter → It is formed from "de-" (meaning down or away) and "fault" (from Old French *faute*, meaning a mistake or failure). The suffix "-er" indicates a person who performs an action. A defaulter is therefore a person who fails to fulfill an obligation or duty.
Think of someone who has 'failed' ('fault') to meet their responsibilities, and the 'de-' suggests a downward movement away from what is expected.
