sneak peak (sneak peek)

Not sure whether to write sneak peek or sneak peak? They sound the same, but only sneak peek fits the meaning of a quick or secret look. Below are clear rules, memory tricks, and many ready-to-copy examples for work, school, and casual use.

Quick answer

Use sneak peek. Peek means a quick or secret look; peak means the highest point. Write, for example, "Take a sneak peek at the new design," not "Take a sneak peak."

Peek = a quick glance. Peak = the top or highest point.
Correct phrase: "take a sneak peek."
If unsure, replace with "quick look" - if that reads naturally, use peek.

Core explanation: peek vs. peak

Peek functions as a noun or verb meaning a quick or furtive look: "take a peek," "peek through the curtain." Peak refers to a summit or to reaching the highest point: "mountain peak," "sales peaked in July."

Because sneak peek means a brief, secret look, peek is the only correct choice in that phrase. Using peak either changes the meaning or creates a nonsensical phrase.

Peek = look quickly or furtively.
Peak = summit, highest point, or to reach a top level.

Wrong: Take a sneak peak at our new menu.
Right: Take a sneak peek at our new menu.
Wrong: Don't peak at your birthday presents!
Right: Don't peek at your birthday presents!

Grammar details: parts of speech and why peek fits

Memory trick: how to never mix them up again

PEEK has two E's - imagine two eyes peering through a peephole. PEAK contains an A like APEX - think top. Quick checks: swap the phrase with "quick look" - if it fits, use peek. If the meaning is "top," use peak.

Mnemonic: peek = two E's = two eyes peeking.
Proof: replace with "quick look" - if it reads well, choose peek.

Similar mistakes to watch for

Peek can be confused with peep and pique. Peep is a close, slightly more informal synonym (also a small sound or creature). Pique (with q) means to arouse interest or irritation and is unrelated to looking.

Also avoid redundancy: sneak peek preview is repetitive - choose either sneak peek or sneak preview.
