Three words, one pronunciation, three completely different meanings — and one of the most misspelled trios in English. “Sneak peak” is wrong the vast majority of the time it’s written, and “peaked my interest” makes editors wince. Here’s how to never mix them up.
Peak vs Peek vs Pique: The Short Answer
Peak = the highest point or to reach the top. Peek = a quick, sneaky look. Pique = to spark curiosity or interest (or, as a noun, a fit of resentment). “Take a sneak peek at the mountain peak — I hope it piques your interest.”
Peak: The Highest Point
Peak is about tops and maximums. As a noun, it’s the pointed top of a mountain — and by extension, the highest level of anything: peak performance, peak season, peak traffic, the peak of someone’s career. As a verb, it means to reach that maximum: “Sales peaked in December,” “The outbreak peaked last winter.”
Memory trick from Merriam-Webster: the a in peak matches the a in maximum — and a capital A itself looks like a mountain. When you’re talking about heights, summits, or highest levels, peak is always the word.
- “We reached the peak just as the sun rose.”
- “Her career peaked with that award-winning role.”
- “Traffic peaks between 8 and 9 a.m.”
Peek: A Quick, Sneaky Look
Peek is about looking — quickly, furtively, or through a small opening. You peek through a keyhole, peek at your presents before wrapping, take a sneak peek at a trailer. It’s both noun (“take a peek”) and verb (“she peeked inside”).
Merriam-Webster’s memory trick: you peek in order to see — the double e is the pair of eyes doing the looking. If eyes are involved, it’s peek.
- “He peeked through the curtains to see who was at the door.”
- “Here’s a sneak peek at next week’s episode.”
- “No peeking while I hide the gifts!”
The single most common error in this trio is writing “sneak peak” — one widely shared analysis found the wrong spelling outnumbers the right one by a huge margin. There is no such thing as a “sneak peak.” It’s always a sneak peek.
Pique: To Spark Interest (or a Fit of Resentment)
Pique is the oddball. It comes from a French word meaning “to prick” — and its meanings all involve something sharp touching you:
- Verb: to stimulate interest or curiosity. “The trailer piqued my interest.” This is the most common modern use — and the source of the second-most-common error: writing “peaked my interest” or “peeked my interest.” Only pique arouses curiosity.
- Verb (especially British): to arouse anger or resentment. “Their rudeness piqued him.”
- Noun: a transient feeling of wounded vanity — a fit of resentment. “She left in a fit of pique.”
- Verb phrase: to pique oneself on — to take pride in. “He piques himself on his grammar.”
Memory trick: pique shares its -ique ending with technique, antique, and unique — it’s the fancy French one, for the fancy concept of stimulated curiosity. A sharp prick of interest.
The Mistakes Everyone Makes
| Wrong | Right | Why |
|---|---|---|
| sneak peak | sneak peek | A preview is a look, not a mountain |
| peaked my interest | piqued my interest | Only pique stimulates curiosity |
| peeked my interest | piqued my interest | Same — curiosity isn’t a glance |
| at the peek of his career | at the peak of his career | Career highs are summits |
If you can master this trio, you join a rare club — these three sit alongside rain vs rein vs reign and pedal vs peddle vs petal in the hall of fame of English homophone traps.
Frequently Asked Questions
Peak = highest point (noun) or to reach the top (verb). Peek = a quick or secretive look (noun/verb). Pique = to stimulate interest or curiosity (verb), or a fit of resentment (noun).
“Sneak peek” — always. A preview is a secret look, so it’s peek (peek to see). “Sneak peak” is one of the most common misspellings in English.
“Pique my interest.” Only pique means to stimulate curiosity — it comes from French for “to prick,” like a sharp prick of interest. “Peak my interest” and “peeked my interest” are both wrong.
It means in a sudden fit of resentment or wounded pride — storming off because your feelings were hurt. The noun pique is “a transient feeling of wounded vanity.”
To take pride in something. “She piques herself on her punctuality” means she prides herself on being on time. It’s a less common but still correct use.
Like “peek” — all three words are pronounced identically. That’s exactly why the spelling matters so much: only the letters tell your reader which one you mean.
