Peak, peek and pique all sound the same, so spelling is the only clue. The phrase to watch is pique your interest. It is not "peak your interest" or "peek your interest", even though both sound right when you say them.
- Peak: the highest point. The peak is covered in snow.
- Peek: a quick, often secret look. Take a peek at my drawing.
- Pique: to arouse interest or curiosity. The title piqued my curiosity.
Peak: the highest point
Peak is the top of a mountain, or the highest point of anything. It is also used as an adjective (peak time) and as a verb (to reach the highest level).

Snow covered the peak all winter.
Traffic is worst at peak time.

Peek: a quick look
Peek means a short look, often a secret one or through a small gap. It is a verb and a noun.
Take a peek at my new drawing.

No peeking during the game!
The sun peeked out from behind the clouds.
Pique: to arouse interest
Pique means to make someone curious or interested. The two phrases to know are pique your interest and pique someone's curiosity. It is a verb, so the past form is piqued.
The title piqued my curiosity.
A strange noise piqued her interest.
That mystery book really piques my interest.
The poster piques everyone's curiosity.
Easy way to tell them apart
Ask: is it a mountain top, a quick look, or interest?
- The top, or the highest point? Use peak.
- A quick look? Use peek.
- Curiosity or interest? Use pique.
💡 The OddLingo Trick
- Peek has two es, like two eyes taking a look.
- Pique has a q, and a piqued interest makes you ask a question. Q for question.
- Peak is the top, like a mountain. Nobody climbs to a peek.
