Etymology

The word "stalker" originates from the verb "stalk," which traces back to Old English stealcian ("to walk cautiously or stealthily"), akin to Old Norse stelkr ("a stalk, support"). The agent suffix "-er" transforms the action into a person who performs it. Over time, "stalker" evolved from describing literal hunters or predators to its modern connotation of obsessive pursuit, particularly in human contexts. The botanical sense of "stalk" (plant stem) is a separate semantic branch.
