The prefix "semi-" means "half", and the standard tractor-trailer articulated vehicle is called a "semi" because of the trailers they pull.
A "full" trailer has wheels in the front and back, like a railway car, and connects to the tractor from the front. A "semi-trailer" (or, essentially, "half-trailer") only has wheels in the back, and the front sits over the back wheels of the tractor pulling it.
A vehicle with 18 wheels is commonly known as a "semi-truck" or "tractor-trailer."
