Life insurance is a type of insurance that provides financial protection to those who rely on a person's income. Synonyms for life insurance include protection insurance, life assurance, and term assurance. Protection insurance refers to coverage that safeguards a family's income in case of an unexpected event, while life assurance typically refers to a more comprehensive policy that protects against death or debilitating injury. Term assurance is similar to life assurance but covers only a specific period and may require periodic renewal. Regardless of the term used, life insurance is an essential part of financial planning and can provide a sense of security to those who depend on the insured person for their financial needs.
