Etymology: "Peeker" is a plain formation: the verb "peek" with the agent suffix "-er," so it names one who peeks. "Peek" itself is the older and more fundamental word, and it has a notably humble pedigree, having been used for centuries to mean a quick, sideways look, often furtive, before "peeper" or "peeker" took on the sense of someone spying from hiding. The suffix does the same job it does in "baker" or "walker," turning an action into the person performing it. A peeker is therefore someone whose habit is peeking, which is why the word sits comfortably beside "snooper" and "spy" in the sense of a secret observer. The meaning stays close to the physical act of glancing through a gap, keyhole, or curtain.

Synonyms: glancer, snoop, spyer, observer, watcher
