IPA: /nɒnɪnˈʊəd/
KK: /nɑnɪnˈʊrd/
Describing someone or something that does not have insurance coverage.
Many people are concerned about the risks of being noninsured in case of an accident.
Noninsured → It is formed from "non-" (meaning not) and "insured" (from Latin "securare", meaning to make secure or safe). The word "noninsured" refers to someone or something that is not covered by insurance, hence not secure or safe in that context.
Think of 'not' ('non-') being added to 'insured', which means not having insurance coverage, so you are not secure.
