TOEIC Link Part 5: waive versus waiver

Waive and waiver come from the same root and sound nearly identical, yet they belong to different parts of speech. Waive is a verb meaning to give up a right, claim, or requirement voluntarily; a waiver is a noun naming the act of waiving or the document that records it. Because business and legal contexts use both constantly, Part 5 likes to slot the wrong form into a blank and reward a reader who processes only the sound. For a pair separated by grammatical role in the same way, see waive versus wave.

The core rule: an action versus the record of it

• waive (verb) = to give up a right or requirement voluntarily — it performs an action. The bank agreed to waive the transfer fee. / Attendees may waive the deposit if they register early.
• waiver (noun) = the act of waiving, or the document that records it. Please sign the waiver before the tour begins. / The customer requested a waiver of the late charge.

The clue is the word's grammatical job. Waive is a verb — it takes a subject and an object and is often preceded by an auxiliary such as will, may, or agreed to. Waiver is a noun — it names a thing and can follow an article (a, the) or a possessive.

Why Part 5 likes this pair

The two words fill different grammatical slots, so the sentence structure usually decides the answer.

The airline has agreed to __ the change fee for affected passengers.

The blank follows agreed to and needs an action word, so the answer is waive.

Guests must sign a liability __ before using the equipment.

Here the blank follows the noun phrase a liability and names a document, so waiver is required.

Spotting the clue in the structure

Ask whether the word performs an action or names a thing:

• It follows an auxiliary or to and takes an object → it is a verb, so choose waive (will waive, may waive, agreed to waive the fee).
• It follows an article, an adjective, or a possessive → it is a noun, so choose waiver (a waiver, the signed waiver, their fee waiver).

A quick test settles most items: if you could swap in give up or drop, you want the verb waive; if you could swap in exemption or release form, you want the noun waiver. For another pair decided by whether the blank is a verb or a noun, see device versus devise.

Quick self-check

1. Management decided to __ the penalty for first-time customers. (waive — give up)
2. Every participant returned a signed __ to the front desk. (waiver — the document)

Takeaway

If the blank is a verb meaning to give up a right or requirement, you need waive. If it is a noun naming the act or document of giving it up, you need waiver. Decide whether the sentence performs an action or names a thing, and two similar-sounding words stop competing.
