Skulk(verb)- to move or hide in a secret way especially because you are planning to do something bad.
This was found in âThe Yellow Wallpaper,â on page 61, in the 10th paragraph. âBut in the places where it isn’t faded and where the sun is just soâI can see a strange, provoking, formless sort of figure, that seems to skulk about behind that silly and conspicuous front design.â
The narrator notices the figure secretly moving or hiding in the wallpaper, otherwise known as the woman, which she believed was trying to escape.
