IPA: /ˌriːɪnˈʃʊərəns/
KK: /riːɪnˈʃʊərəns/
A type of insurance that insurance companies buy to protect themselves from large losses by sharing the risk with other insurers.
The insurance company decided to purchase reinsurance to reduce its financial risk.
Reinsurance → It is formed from "re-" (meaning again) and "insurance" (from Old French *ensurer*, meaning to make sure or secure). The word "reinsurance" means the act of securing again, typically referring to insurance taken out by an insurance company to mitigate risk.
Think of 'securing again' — 're-' means again, and 'insurance' means to make sure. This helps you remember that reinsurance is about making sure again.
