Other forms: lurking, lurks, lurked
To lurk is to wait somewhere out of sight, watching, up to no good. A figure in the doorway across the road who has been there twenty minutes; a cat flattened under a parked car, waiting for the pigeon to hop closer.
Lurk carries suspicion with it, which is why nobody lurks at a bus stop, they wait. Things lurk as well as people: a doubt lurks at the back of your mind, a bug lurks in the code, a smell lurks in a fridge and refuses to be found. It has a fixed shape — something lurks behind, beneath, in or around. Online the word lost its menace altogether: to lurk in a forum or a chat is to read everything and post nothing, and a lurker is a harmless regular who has been there for years without saying a word.

Lurk came into Middle English as lurken from Old Norse lúrka, and the Germanic word behind it means what the English one still means: to be lying in wait. It is built on lour, the verb for a sky or a face gone dark and threatening. Its cousins across the North Sea kept the sneaking too — West Frisian luorkje, to lurk, and Middle Low German lûrken, to stalk somebody deceitfully.
