What does warranty mean?
A warranty is a promise or assurance attached to a product, service, property, or legal transaction. In everyday consumer use, it means that the manufacturer or seller will be responsible for correcting specified defects or failures during a defined period, subject to the contract’s exclusions and conditions. Warranties may be provided automatically by law in some circumstances, included with a purchase, purchased separately, or offered to extend coverage. The word also has a legal sense: a warranty of title or authority is an assurance that a particular statement is true. Unlike a general guarantee, a warranty is usually tied to specific conditions and obligations. The term is useful because it distinguishes a defined promise of protection or accuracy from an informal expression of confidence, while its legal meaning has long been important in contracts, sales, and property transfers.
nounA warranty is a contractual or legal assurance that a product, service, or property will meet specified conditions or perform as promised. In consumer contexts, it usually describes the period during which the manufacturer or seller is responsible for repairing, replacing, or refunding a defective product, subject to the terms of the agreement.
- A contractual assurance covering the quality, condition, or performance of a product or service, usually for a stated period.
- A legal assurance or undertaking, such as a warranty of title or authority, that a stated fact is true.
"The camera came with a two-year manufacturer’s warranty, so they returned it when the lens began to malfunction."
"The appliance is still under warranty, so the manufacturer will replace the faulty heating element."
"The seller provided a written warranty that they had clear title to the property."
The standard plural adds -ies: warranty becomes warranties.
"The manufacturer offers warranties on several different models."
A warranty turns a purchase into a promise: if the covered product fails as described, the terms determine who must put things right.
