# insurance terms, pointed earlier

*premium, policy, claim, deductible, underwriting, exposure — what each word means, and what it becomes when the money moves before the loss*

**Insurance terms** are the working vocabulary of property and casualty insurance — eight on the policy itself, six behind it. They say what is covered, what you pay, what you get after a loss, and what the insurer keeps out. Each is defined as an underwriter would — then shown what it becomes when the money is paid before the loss instead of after.

The hillside above the house, the wetland above the river town, and the forest around the reservoir do their work — holding soil, slowing water, keeping the slope — whether or not anyone writes a policy or holds a certificate. Insurance pays when that work fails. [**Ensurance**](/manual/ensurance?from=guide) pays for the work while it is still being done. Neither one is the hill.

## the fourteen terms, in the insurance sense

These are the insurance meanings, untouched. An underwriter should be able to sign off on every line.

**Premium** is the price a policyholder pays an insurer for coverage over the policy term, billed monthly or annually. It is set from expected loss — how often a loss happens times how bad it tends to be — plus expenses and a margin.

**Policy** is the written contract between the insurer and the insured: what is covered, for how much, for how long, and under what conditions, including exclusions and any endorsements.

**Policyholder / insured.** The policyholder owns the contract and pays the premium; the insured is whoever's loss it covers. Usually the same party, not always — a contractor's liability policy often names the project owner as an additional insured. An insured must hold an insurable interest — a real stake in the thing covered.

**Claim** is a formal request to the insurer for payment after a loss the insured believes is covered. An adjuster investigates cause and amount, applies the policy's terms, and the insurer pays what is owed, up to the limit.

**Deductible** is the amount the insured absorbs on each loss before the insurer pays anything. A higher deductible lowers the premium; on wind, hail, and earthquake it is often a percentage of insured value.

**Limit** is the most the insurer will pay for a covered loss — per occurrence, and often in aggregate over the term. Sublimits cap categories inside it, such as mold.

**Exclusion** is a peril, property, or circumstance the policy says it will not cover. Flood and earthquake are excluded from a standard US homeowners policy and bought separately, if at all.

**Underwriting** is evaluating a risk, deciding whether to accept it, and setting terms and price if so. It happens before a policy is bound and again at each renewal — where non-renewal comes from.

**Exposure** is the amount an insurer stands to lose across the policies it has written: the insured value in a hurricane zone, the homes in one fire corridor. It is also the unit premium is rated on — payroll, vehicle-years, square footage. For an insured, it is the loss they would face.

**Pool** is the premiums of many policyholders held together so the losses of the few are paid from the contributions of the many. Across enough independent risks, losses become predictable even when no single one is ([what insurance actually is](/guide/what-insurance-actually-is?from=guide)).

**Reinsurance** is insurance for insurers. An insurer cedes part of its risk to a reinsurer so one very large loss, or many at once, does not break its balance sheet: proportional (quota share) splits premium and losses; excess of loss pays above a retention, for its own price.

**Loss ratio** is losses and loss-adjustment expense divided by earned premium, before investment income. Add the expense ratio and you have the combined ratio; above 100 percent, the insurer lost money on underwriting alone.

**Parametric** describes a policy that pays a pre-agreed amount when a measured index — wind speed, rainfall, earthquake magnitude — crosses a threshold, rather than after an adjuster assesses the loss. It pays fast. It can also pay nothing when the index misses a real loss, or pay when little was lost: basis risk.

**Captive** is an insurance company owned by the business (or group of businesses) it insures, formed to retain risk the parent would otherwise buy in the market. It is a regulated insurer with capital and reserves.

Premium, claim, deductible, limit, exclusion — each is a sentence about a loss that has happened, or is priced as if it will. That is the design: insurance makes a loss survivable by writing the terms of the aftermath in advance. The hillside is in none of these definitions. The policy sits on the slope that keeps the house there, and nothing in the contract pays the slope.

**every insurance term is written around the loss.** Pointed earlier, the same words describe money that moves into the place before one.

## the same words, pointed earlier

An **account** is what a place or a purpose holds in its own name — a wetland, a watershed program. A **certificate** is a recorded share in the funded present condition of one named place, people, or purpose: a **policy** when the place is titled and its owner is cooperating, a **line** otherwise ([certificates](/manual/certificates?from=guide)).

Tags: *extended* — same job as at Lloyd's, applied to a place instead of a risk; *refreshed* — the word is kept, the physics change; *proposed* — named in design, not live; *not applicable* — ensurance has nothing for the word to do, and the row says why.

| term | in insurance | pointed earlier (in ensurance) |
|---|---|---|
| **premium** | The price of a promise to pay after a loss. | *refreshed* — A recurring payment on a policy certificate that funds the place's protection now and can build toward permanent protection. Policies only; a line carries no premium. |
| **policy** | A contract of indemnity for a named insured. | *refreshed* — A certificate on a titled place whose owner is cooperating, written with the owner, on a path to entrust: permanent protection under real property law. |
| **line** | A share of one risk; also a line of business. | *refreshed* — A certificate for a place without a cooperating titleholder, or for a people or a purpose. Ensured to varying degrees; it can lapse. Not a participation percentage, not a category of business. |
| **policyholder / insured** | Who owns the contract; whose loss is covered. | *refreshed* — A policyholder is a member holding a policy certificate. The ensured is the place itself and, through it, everyone downstream. |
| **claim** | A demand for payment after a loss believed covered. | *refreshed* — What a place's account declares about itself — purpose, mandate, place — beside holdings and activity anyone can read. Condition evidence is designed, not live. Not a demand after a loss. |
| **underwriting** | Whether to accept a risk, and on what terms. | *extended* — Deciding a place is worth ensuring and on what terms: assessment, valuation, monitoring. Continuous, not a one-time acceptance. |
| **exposure** | The insurer's potential loss across its policies. | *refreshed* — The dependent's downside when a place declines: the town's, the utility's. Same word, opposite direction along the dependency. |
| **pool** | Many premiums held so the few are paid by the many. | *refreshed* — A [syndicate](/guide/ensurance-syndicates?from=guide): accounts pooling capital toward one theme, such as [wildfire resilience](/wildfire-resilience.syndicate?from=guide). Shared funding of condition, not a reserve against indemnity. On this site [pools](/pools?from=guide) also names trading liquidity — a different thing. |
| **reinsurance** | Insurance for insurers. | *proposed* — No instrument yet; a re-ensurance layer behind a place's funding is described, not built. A reinsurer can take part as a payor, not as a layer. |
| **loss ratio** | Losses and adjustment expense over earned premium. | *proposed* — A stewardship ratio: money deployed into the work of the place against premiums received. Insurers manage the loss ratio toward a target; this one would be read high. Named, not built, not reported. |
| **parametric** | A set payout when an index crosses a threshold. | *proposed* — Funds released into a place's work when an indicator says it is time: a drought index, a fuel-moisture reading. Same trigger; the cash would move into the place, not to a claimant. Designed, not live. The insurance version: [the payout that misses the place](/guide/the-payout-that-misses-the-place?from=guide). |
| **captive** | An insurer owned by the business it covers. | *proposed* — A company's own account funding the upstream place it depends on: the watershed above the plant. The account and the certificates are live; calling that arrangement a captive is a proposal. Beside an actual captive, ensurance is a sleeve: [put nature in the captive](/guide/put-nature-in-the-captive-not-just-the-claims-file?from=guide). |
| **deductible** | The share of each loss the insured absorbs first. | *not applicable* — There is no payout to subtract from. The money goes into the place first; nothing is owed, so nothing is withheld. |
| **limit** | The most the insurer will pay. | *not applicable* — A limit caps what is owed after a loss. A certificate owes nothing after a loss; its value follows the place's condition and the market, with no cap promised and no floor. |
| **exclusion** | What the contract will not pay for. | *not applicable* — Exclusions carve a contract down to named perils. A policy certificate funds the whole place as one unit — soil, water, slope, habitat. Outside the boundary is another place, not an excluded peril. |

## the word agent

One more word collides hard. In insurance, an **agent** is appointed by one or more insurers to sell their policies, for commission; a broker represents the buyer. Here, an agent is the account a place or a purpose holds in its own name — the wetland's account — which receives funding, pays stewards, and carries the claims above. One sold you the policy. The other is the party the certificate is on. On this site, read it as the second.

## one lineage, one problem

The oldest words here — policy, premium, line, underwriting — were coined to price what the sea might take. At Edward Lloyd's coffee house after 1688 each name signed his own line on a ship's slip, on his own money, and that vocabulary has been extended here, not taken ([how an industry gets born](/guide/how-an-industry-gets-born?from=guide)). The full working definitions — slip, ensured, entrust — live on [ensurance](/manual/ensurance?from=guide) and [certificates](/manual/certificates?from=guide) in the manual.

The words are shared because the problem is shared. A ship at sea carried value no deed or contract on land could see, and it was financed anyway. A wetland's water crosses the parcel line, the county line, and every balance sheet below it, and no deed or contract sees that either. Insurance pays for what was lost. Ensurance pays for what is still working. The two stack: the condition makes the loss smaller; the policy covers what still arrives.

## what to do with the list

The tally: one word extended, seven refreshed, four proposed and marked so, three with no job to do.

Insurance wrote the grammar for a loss. Pointed earlier, the same grammar describes the slope still holding. Keep the policy on the house — then read [what ensurance cannot do](/guide/what-ensurance-cannot-do?from=guide); the limits are where the two meet. Live certificates, place by place: [specific ensurance](/specific?from=guide). The rest of the vocabulary: the [manual](/manual?from=guide).

## frequently asked questions

### what are the most important insurance terms to know?

Premium, policy, deductible, limit, exclusion, and claim: what you pay, what you hold, what you absorb, the most you can get, what is left out, and how you ask. Underwriting and exposure explain the price; pool, reinsurance, and loss ratio explain solvency.

### what is the difference between a premium and a deductible?

A premium is what you pay the insurer, on a schedule, whether or not a loss happens. A deductible is what you pay yourself, per loss, before the insurer pays. Raising the deductible usually lowers the premium.

### what does underwriting mean?

Underwriting is the insurer's decision about a risk: whether to take it, at what price, with which terms and exclusions. It draws on the application, loss history, models, and inspections, and repeats at renewal. A non-renewal is an underwriting decision.

### what is exposure in insurance?

Exposure is what an insurer could lose — the value it has promised to cover in an area or against a peril — and the unit premium is rated on. Heavy exposure in one fire corridor is correlated risk: one event hits many policies.

### what does premium mean in ensurance?

In **ensurance** a premium is a recurring payment on a policy certificate — a certificate on a titled place whose owner is cooperating. It funds that place's protection now and can build toward permanent protection. Lines carry no premium. It is not the price of a promise to pay later; nothing pays out after a loss ([ensurance](/manual/ensurance?from=guide)).
