When do we use "peek"?
Although we stated above that both "peak" and "peak" can appear both as nouns and verbs in sentences, "peek" is actually a lot less used as a noun. In other words, "peek" only appears as a noun in a certain expression, and that is "having/taking" a peek, which means to look at something for a short while. "Peek" is in general used as a verb, and it defines the action of looking at something for a short while, usually not wanting other people to see you.
Example 1: I only had a peek to see what they were doing; I couldn't see well. "Peek" is only used as a noun in the exemplified expression, referring to the same action that the verb "peek" refers to: looking at something for a short time.

A short trick to remember which word means what is to keep in mind that "peak" contains an "a". Think about the form of the letter "A" - it's just like a mountain, or like the peak of the mountain. That is a great clue to trigger your memory to remember that "peak" refers to the highest value or level of something, or to the top of a mountain.
Once you know what "peak" means, you'll also figure out that "peek" carries the other definition, which is looking at something for a short while, usually from a hidden spot.
