What does adjuster mean?
An adjuster is most commonly a professional who investigates insurance claims, inspecting damage, gathering evidence, and determining how much compensation the insurer owes. In American English this figure is usually called simply an adjuster or claims adjuster, while British English favours loss adjuster; a public adjuster represents the policyholder rather than the insurance company. Beyond the insurance world, adjuster also names any device that alters position, tension, or setting — the buckle-like adjuster on a backpack strap, for example. The word derives from the verb adjust, which traces back through French ajouter-related forms to Latin adjuxtare, meaning to bring near or set right. Because it combines human judgement with technical precision, the word carries connotations of careful evaluation and fair settlement, making it essential vocabulary in both insurance and everyday hardware contexts.
A person employed to investigate and settle insurance claims, assessing losses and determining the amount to be paid.
"The adjuster reviewed the repair estimates before issuing a settlement offer."
Standard term in US insurance; British English typically uses 'loss adjuster'.
A device or mechanism that alters the position, tension, or setting of something.
"Pull the adjuster to shorten the strap."
Regular plural; used when referring to multiple insurance professionals or multiple adjusting devices.
"Three adjusters were dispatched to evaluate the flood damage across the region."
In Britain, the same professional is called a 'loss adjuster' — so if your claim is denied, you literally lost to a 'loss' expert.

Etymology of adjuster
Adjuster derives from the verb adjust, formed from the Latin adjuxtare ('to bring close to, set right'), built on ad- ('toward') and juxta ('near'). The verb entered English via Old French in the late Middle Ages, and the agent noun adjuster developed naturally from it, first appearing in English around the early modern period. Its specialized insurance sense became established in the nineteenth century as the modern insurance industry grew. Cognate forms sharing the same Latin root include adjustment, adjustable, and, more distantly, words like juxtapose, which comes from the same Latin juxta.
