Peek or peak

Peek and peak are commonly confused words because, despite having different meanings, they are pronounced in the same way (i.e., they are homophones).

A “peek” is a quick, often secretive, “look.” So, if you have trouble remembering which is which, remembering that “peek” and “see” are both spelled with double “e” and are related in meaning might help.

The verb “peek” is frequently used with the prepositions “out of,” “into,” “through,” and “around.” It can be used figuratively to refer to an object that is partially hidden.
