Waiver
Etymology
From Anglo-French “weyver” (to abandon or give up), related to “waif” — an ownerless, abandoned thing. To waive a right is to treat it as a waif: to let it go unclaimed and abandoned.
noun · /WAY-vur/
A voluntary and knowing surrender of a legal right or claim, often in writing.
What it names
The fine print where you sign away a right — reach for it when a form asks you to give up your ability to sue or complain later.
Example
Before the bungee jump, every participant had to sign a waiver releasing the company from liability.
Related idea
A waiver gives up a right you hold; a warranty does the opposite by adding a promise you can rely on — signing a broad waiver can quietly cancel out protections you assumed you had.
