Okay, I found this:
"Semi-trailer is the name of the kind of trailer that a prime mover pulls, but in general use refers to the whole assembly. "Semi" refers to the fact that when attached to the tractor unit the cargo is half supported by the rear wheels of the tractor." (from the folks at ApparelSearch [what they are doing defining it, I have no idea...])
Now, I don't know about you, but I feel better... :-)
