What does stalker mean?
A stalker is someone who follows or watches another person persistently, often secretly and in a way that causes fear or feels intrusive. The word also has a traditional hunting sense: a stalker approaches prey quietly, waiting for the right moment to capture or attack it. In contemporary English, the threatening social meaning is especially common, particularly in references to a stalker of a celebrity, an ex-partner, or someone who repeatedly appears in another person's daily life. Because the word often implies unwanted attention rather than ordinary observation, it normally carries a strongly negative emotional and legal association. The related verb “stalk” describes the conduct itself: following, watching, or approaching someone or something in a persistent, often covert manner.
A person who stalks prey, especially one who hunts by following an animal quietly and waiting to attack it.
"The stalker waited motionless beside the path as the herd approached."
This is the traditional hunting sense and is less common in everyday conversation than the threatening modern sense.
A person who persistently follows, watches, or harasses another person, often secretly or in a threatening manner.
"The woman was stalked for months before police finally intervened."
The modern sense is usually negative and can imply obsessive, intimidating, or unwanted attention.
The standard plural adds “-s”; in the threatening modern sense, the plural is commonly used to refer to multiple people who pursue or harass someone.
"The report described how the stalkers followed her across the city."
A stalker does not merely follow someone—it turns watching into pursuit.

Where does stalker come from?
The word “stalker” was formed in English by adding the suffix “-er” to “stalk.” “Stalk” comes from Old English “stalu,” meaning a stem, base, or supporting part, and the noun developed through the sense of an animal's stalk or the act of following game. The modern threatening sense developed alongside the older hunting and observing meanings.
