stalking

When someone is stalking another person, they're often following them secretly or persistently trying to get their attention.

Stalking can be a bit of a tricky word because its meaning has changed over time. In the past, it just meant walking with a slow and steady pace, but now it's more commonly associated with unwanted or obsessive behavior. A celebrity might complain about being stalked by paparazzi following her everywhere she goes. In this sense, stalking is all about invading someone's personal space.

In some cases, especially in the context of law enforcement, "stalking" can also refer to a specific crime where someone follows or harasses another person with intent to intimidate or cause harm. It's worth noting that in general conversation, people often use the word "stalk" or "stalker" to describe anyone who is excessively following or pursuing another person, even if it's not necessarily a serious crime.
