Insurance Terms, Explained in Plain English

Insurance policies are written in a language nobody speaks at the dinner table. This glossary translates the 48 terms you'll actually run into — on your declarations page, in a quote, or during a claim — into plain English, each with a direct definition, a worked example, and answers to common questions. Every entry is reviewed by Evan Larson, a licensed insurance agent at Better Choice Insurance Group, an independent agency in St. Charles, Illinois.

Auto Insurance Terms

• Bodily Injury Liability — Pays other people's medical bills and related damages when you cause an accident.
• Property Damage Liability — Pays to repair other people's vehicles and property you damage in an at-fault accident.
• Collision Coverage — Pays to fix your own car after a crash, regardless of fault, minus your deductible.
• Comprehensive Coverage — Covers non-crash damage to your car: theft, hail, fire, vandalism, and animal strikes.
• Uninsured Motorist Coverage — Steps in when an at-fault driver has no insurance — or flees the scene.
• Underinsured Motorist Coverage — Covers the gap when an at-fault driver's insurance limits are too low for your injuries.
• Medical Payments Coverage — No-fault coverage that pays medical bills for you and your passengers after a crash.
• Personal Injury Protection — No-fault coverage for your medical bills, lost wages, and essential services after a crash.

Home Insurance Terms

• Dwelling Coverage — The part of a home policy that pays to rebuild the structure of the house itself.
• Other Structures Coverage — Covers detached structures like fences, sheds, and detached garages.
• Personal Property Coverage — Covers your belongings — furniture, clothes, electronics — at home and often away from it.
• Loss of Use Coverage — Pays extra living expenses when a covered loss makes your home unlivable.
• Personal Liability Coverage — Home-policy protection when you're legally responsible for someone else's injury or property damage.
• Actual Cash Value — An item's replacement cost minus depreciation — what many policies pay for older property.
• Replacement Cost — Pays what it costs to replace damaged property new, without deducting depreciation.
• Extended Replacement Cost — Adds a cushion above your dwelling limit if rebuilding costs more than expected.
• Guaranteed Replacement Cost — Pays the full cost to rebuild your home, even beyond the policy's dwelling limit.

• HO-5 Policy — A broader homeowners form with open-peril coverage on both the house and your belongings.
• HO-6 Policy — The condo policy: covers your unit's interior, your belongings, and your liability.
• Named Peril vs Open Peril — Whether a policy covers only listed causes of loss — or everything not excluded.
• Water Backup Coverage — Covers damage when water backs up through drains, sewers, or a failed sump pump.
• Service Line Coverage — Covers repairs to buried utility lines — water, sewer, power — on your property.

• Scheduled Personal Property — Lists high-value items — rings, art, instruments — for broader, itemized coverage.

Life & Umbrella Terms

• Term Life Insurance — Life insurance for a set period — a payout only if you die during the term.

• Deductible — The amount you pay out of pocket on a claim before your insurance pays the rest.
