The Quick Distinction
- Waver: a verb (sometimes a noun) meaning to hesitate, be indecisive, fluctuate, or move unsteadily.
- Waiver: a noun (sometimes a verb in legal contexts) meaning the voluntary relinquishment of a right or claim, or a document formalizing that relinquishment.
Waver: To Hesitate or Fluctuate
Waver comes from Old Norse vafra, meaning to wander. It describes movement between states — between decisions, between positions, between resolutions — without settling.
As a verb:
- She did not waver in her commitment to the project.
- His confidence began to waver under questioning.
- The committee wavered between two options for weeks.
- His voice wavered as he delivered the news.
- The company's stock price wavered throughout the morning.
As a noun (less common):
- There was not a waver of uncertainty in her response.
The adjective form is wavering: a wavering commitment, wavering support.
Waiver: Relinquishing a Right
Waiver comes from the Anglo-French legal term weyver (from waive). It refers to the voluntary giving up of a known right, claim, or privilege — and to the formal document that records that relinquishment.
As a noun:
- Participants were required to sign a liability waiver before the event.
- The company requested a waiver of the standard filing deadline.
- She signed a waiver acknowledging the risks involved.
- The athlete was claimed off waivers by another team. (sports context)
- A fee waiver was granted based on financial hardship.
The verb form is waive: to voluntarily give up a right.
- She agreed to waive her right to appeal.
- The fee was waived for eligible applicants.
The Connection: Waive → Waiver
Understanding the relationship between waive and waiver helps prevent confusion:
- Waive (verb): to give up a right voluntarily
- Waiver (noun): the act of waiving, or the document that formalizes it
- Waver (verb): entirely unrelated — to hesitate or fluctuate
The spelling difference is the final letters: waver ends in -er (verb suffix); waiver ends in -iver (derived from waive + -r).
Common Errors

Memory Trick
Think of waive + r = waiver. The legal document comes from the act of waiving. If you can connect the word to "waive" in meaning, it is waiver with an i.
If the word means hesitation or unsteady movement — like a flame wavering in the wind, or someone wavering in their convictions — that is waver, spelled like the verb with -er.
Frequently Asked Questions
Is "waver" ever used as a noun in legal contexts?
Rarely and carefully. Waiver is the standard legal noun. If you see waver used as a noun in a legal document, it is almost certainly an error for waiver.
Can "waiver" be used as a verb?
The verb form of waiver is waive, not waiver. In some informal or colloquial contexts, people use waiver as a verb ("they waiviered the fee"), but this is nonstandard. Use waive as the verb.
What is a "blanket waiver"?
A blanket waiver relinquishes rights or requirements across a broad category rather than for a single specific instance. In regulatory contexts, a blanket waiver might exempt an entire class of entities from a rule. The word blanket here is an adjective modifying waiver — it's always waiver, not waver.
