Interest is stimulated (piqued), not brought to a summit (peaked).

Mistake 2: "Sneak Peak"

Incorrect: "Here's a sneak peak at the new design."
Correct: "Here's a sneak peek at the new design."

You're taking a secret look (peek), not viewing a mountain (peak). See commonly misspelled words for more.

Mistake 3: "Peek Performance"

Incorrect: "The engine is running at peek performance."
Correct: "The engine is running at peak performance."

Performance reaches its highest point (peak), not a secret glance (peek).

Memory Tricks

The Shape Trick

The letter "A" in peak looks like a mountain peak — pointed at the top. Mountains have peaks (with an A).

The "EE" = Eyes Trick

Peek has two E's — think of them as two eyes peeking at something. You peek with your eyes, and eyes start with E.

The French Connection

Pique has a unique spelling because it comes from French. If the meaning involves stimulating interest or irritation, use the French-looking spelling with "que."

The Phrase Match

• Mountain → peak (A like a mountain)
• Looking → peek (EE like eyes)
• Interest → pique (French-style spelling for a French word)

Summary

Peak (with an A) means summit or highest point—think of the pointed "A" shape. Peek (with double E) means a quick look—think of two eyes. Pique (with "que") means to stimulate or irritate—it's the French one. The most commonly misspelled phrase is "pique your interest" (not "peak" or "peek").
