TOEIC Link Part 5 — peak vs peek vs pique: The Three-Way Homophone Split Sorted by Meaning, Not Sound

Peak, peek, and pique are pronounced identically but do three unrelated jobs, and Part 5 loves stacking all three as options so the sound cannot help you. This guide fixes peak as the highest point, peek as a quick look, and pique as to provoke or arouse, exposes the two idioms TOEIC weaponizes most — peak season and pique interest — maps the business collocations that lock each spelling, and works the distractor logic on workplace examples.

The new product line was designed to ____ the interest of younger commuters. The options offer peak, peek, pique, and peaked, and learners freeze because all three of the base words sound exactly alike yet mean three completely unrelated things — a high point, a quick look, and a spark of curiosity. The answer is pique, and getting there has nothing to do with pronunciation and everything to do with which of three jobs the sentence is asking the word to do. This guide assigns each spelling to its meaning, then drills the two idioms TOEIC recycles most so the shared sound never traps you.

The rule that actually works: one sound, three jobs

Every Part 5 item with this trio resolves the moment you name the job the sentence needs:

  • peak = the highest point (noun) or to reach the highest point (verb). Sales peaked in December. demand reached its peak. Think of a mountain peak — the top.
  • peek = a quick or secret look (noun/verb). She took a peek at the agenda. Do not peek at the results early. The double ee even looks like two eyes peeking.
  • pique = to provoke, arouse, or stimulate — almost always curiosity or interest (verb); as a noun, a fit of irritation (a fit of pique). The demo piqued his interest.

So the test is: name the job. Highest point → peak. Quick look → peek. Spark someone's curiosity → pique. In the opening item, the product is meant to spark interest, so it is pique. You never decide by how it sounds — you decide by which of the three meanings fits. This is the same "let the meaning, not the identical sound, assign the word" discipline that governs complement and compliment, where the choice turns on completing versus praising rather than on the shared sound.

Trap 1: pique interest — the collocation TOEIC recycles most

The single most tested frame in this trio is pique someone's interest (or pique curiosity). Because peak sounds identical and even carries a vaguely "high/intense" feel, learners write the eggcorn "peak someone's interest" — which is simply wrong. Interest is aroused, not elevated to a summit:

  • The teaser campaign ____ enormous interest before launch. → interest was aroused → piqued
  • Her unusual background ____ the recruiter's curiosity. → curiosity was sparked → piqued

The tell: if the object is interest, curiosity, or attention and the verb means to spark or provoke, only pique is correct — never peak, never peek. Locking a homophone to the frozen collocation it lives in is the same procedure that separates wary and weary, where the fixed collocation, not the sound, picks the word.

Trap 2: peak season vs sneak a peek

The second reversal pits the two noun idioms against each other. TOEIC drops peek where peak belongs, or the reverse, because both are common workplace phrases:

  • Hotel rates rise sharply during ____ season. → the busiest, highest-demand period → peak season
  • Employees were allowed a ____ at the redesigned office before the move. → a quick look → peek (often sneak a peek)

The tell: peak attaches to intensity and maxima — peak season, peak hours, peak demand, peak performance. peek attaches to brief looking — sneak a peek, take a peek, a peek behind the scenes. If the blank names a time of maximum activity, it is peak; if it names a glance, it is peek. This "the idiom decides which twin, not the sound" behavior mirrors how the whole giving-up-rights cluster resolves around waive and waiver.

Trap 3: peaked as a verb vs the noun a fit of pique

A subtler trap uses the verb peaked against the rare noun pique. peak verbs freely — sales peaked, traffic peaked — describing something that rose and then reached its top. Meanwhile pique has a noun life meaning a flash of resentment: He left the meeting in a fit of pique. TOEIC occasionally tests this by placing an emotion context:

  • Website traffic ____ during the holiday promotion and then tapered off. → rose to a maximum → peaked
  • She resigned in a fit of ____ after the proposal was rejected. → a flash of irritation → pique

The tell: a rising-then-topping curve of quantity → peaked; a burst of wounded irritation (fixed phrase a fit of pique) → the noun pique. Sorting by the grammatical slot and the frozen phrase, not the sound, is the same logic that untangles precede and proceed, where the job the sentence assigns settles the choice.

The business collocations that lock each spelling

Part 5 pulls this trio from a stable set of workplace frames:

  • peak (highest point) — peak season, peak hours, peak demand, peak performance, peak capacity, off-peak, sales peaked, at its peak.
  • peek (quick look) — take a peek, sneak a peek, a peek behind the scenes, a sneak peek at the roadmap.
  • pique (provoke) — pique interest, pique curiosity, pique attention, a fit of pique (noun).

Two deserve a flag. off-peak — a set adjective for cheaper, quieter, non-maximum periods — comes only from peak: off-peak fares, off-peak hours. And sneak peek — a preview — is a frozen compound; the misspelling sneak peak is one of the most common English errors, and TOEIC exploits it. Match the frozen frame, not the letters. This "the collocation decides, not the parts" behavior mirrors how the demolition cluster resolves around raze and raise.

Worked examples

  1. Advance ticket sales are heaviest during ____ travel season. → the busiest, highest-demand period; peak.

  2. The trailer was released early to ____ audience interest. → to arouse interest; pique.

  3. Reviewers were given an exclusive ____ at the unreleased device. → a quick, privileged look; peek (sneak peek).

  4. Quarterly revenue ____ in Q4 before normalizing in Q1. → rose to a maximum then fell; peaked.

  5. He stormed out in a fit of ____ when his idea was dismissed. → a flash of irritation; the noun pique.

The one-line summary

Highest point → peak. Quick look → peek. Spark curiosity → pique. Name the job the sentence needs and check the frozen collocation; never let the identical sound decide. That single discipline — meaning and slot before sound — is what carries you through the whole confusable family, from the lift/hesitate split around waiver and waver to every homophone TOEIC drops into Part 5.
