Peak vs Peek vs Pique: Three Homophones

Getting Started

Peak, peek, and pique sound the same: /piːk/. On the page, though, they do very different jobs. A peak is a top, summit, or highest level. A peek is a brief look, often a hidden one. Pique is the word you want when something sparks curiosity, stirs interest, or causes annoyance.

The spelling mix-up that shows up most often is "peak your interest". The standard phrase is "pique your interest", because interest is aroused or stimulated, not raised to a mountain top. This dictionary.wiki guide separates the three words with definitions, usage notes, examples, and memory cues.

Correct: "The headline piqued my interest."

Curiosity is stirred or awakened. That means it is piqued, not peaked.

Error 2: Writing "Sneak Peak"

Incorrect: "Watch this sneak peak of the new game."
Correct: "Watch this sneak peek of the new game."

A preview gives you a brief look, so the word is peek. A peak is a top or summit. See commonly misspelled words for more spelling traps.

Error 3: Writing "Peek Performance"

Incorrect: "The laptop is operating at peek performance."
Correct: "The laptop is operating at peak performance."

When performance is at its best, it is at its highest level: peak.

Easy Ways to Keep Them Straight

Use the Shape of A

The "A" in peak has a pointed shape, like a mountain. If you mean a summit, a maximum, or the highest point, choose peak.

Let the Double E Remind You of Eyes

Peek contains two E's. Picture them as two eyes looking at something. If looking is involved, the spelling is usually peek.

Remember the French-Looking Ending

Pique looks different because it comes from French. Use this spelling when something stimulates interest, arouses curiosity, or causes irritation.

Match the Idea to the Spelling

• Interest → pique (the French-derived spelling)
• Mountain or maximum → peak (A is pointed)
• Looking → peek (EE suggests eyes)

Quick Recap

Peak has an A and refers to a summit, top, or highest level. Peek has two E's and means a quick look. Pique has the French-looking que ending and means to stimulate, arouse, or irritate. The phrase to remember is "pique your interest"—never "peak your interest" or "peek your interest."
