Common Mistakes to Avoid

  1. Writing Peek Instead of Peak for Mountain Tops or Highs
    Incorrect: They climbed to the peek of the mountain.

    Explanation: The physical high point or mountain summit is peak (with an 'a'), not a glance (peek).
  2. Writing Peak or Peek Instead of Pique for Interest
    Incorrect: That story really peaked/peeked my interest.
    Correct: That story really piqued my interest.
    Explanation: The phrase meaning to awaken or spark curiosity is always "to pique interest."

Summary

Although peak, peek, and pique sound the same, their meanings belong to entirely different contexts:

  • Peak – The highest mountain top or maximum level (think of the 'A' in peak resembling a mountain peak).
  • Peek – A quick look or secret glance (think of the double 'e's as two eyes exploring).
  • Pique – To spark interest, arouse curiosity, or cause irritation.

A simple memory tip: A mountain peak reaches high like an A-frame, you peeek with two eyes, and pique is a unique spelling for provoking curiosity.
