A "peeper" is a noun referring to an individual who engages in the act of peeping or spying on others, usually in a secretive or surreptitious manner. This term is commonly associated with the act of observing someone, often without their knowledge or consent, through windows, keyholes, or any other means of illicitly gaining a view of a private space.
The term "peeper" is derived from the verb "to peep," which means to secretly look at or observe someone or something. It specifically connotes the idea of looking furtively or pryingly, indicating a lack of respect for personal boundaries and privacy.
In a general sense, a peeper can be someone who has an insatiable curiosity about the private affairs of others and a desire to intrude upon those boundaries. This term is often associated with negative connotations, as the act of peeping is seen as an invasion of privacy, unethical, and potentially illegal, depending on the circumstances.

The word "peeper" has an interesting etymology. It originated in the 14th century from the Middle English word "pipen" or "popen", which meant "to cry like a bird". This term eventually evolved into "pepen" or "peepen" in the 16th century, meaning "to chirp like a chick or bird".
By the 17th century, "peeper" started being used to refer to a chick or a young bird itself. At that time, it was expanded to also describe a baby or a young child. This sense of the word faded away over time, but it continued to be used in dialectal English to refer to the eyes, based on the concept of young birds or chicks with small, bright eyes.
In contemporary usage, "peeper" typically denotes the eyes, especially in informal or colloquial contexts.
