A major pitfall for English speakers is to confuse 边缘 with the English word “edgy.” “Edgy” often implies something is cool, provocative, or avant-garde. 边缘 almost never has this positive connotation. It simply means peripheral or marginal.
Beginners might confuse these two. `旁边` means “beside” or “next to,” indicating proximity. `边缘` refers to the actual boundary or fringe.
