The word "lurking" refers to the act of remaining hidden or concealed, often with the intention of surprising or ambushing someone. It can describe someone who is quietly waiting in the shadows, either for a specific moment to act or to observe without being noticed. In a broader sense, it can also relate to being present but not actively participating, particularly in online contexts, like someone who reads posts in a forum without commenting.
The word "lurking" comes from the Middle English "lurken," which means to lie in wait, often suggesting a sense of stealth or hidden presence. Its origins can be traced back to the Scandinavian languages, particularly Old Norse "lurkr," meaning "to lurk" or "to hide."
