LINGUISTICS DESK: As part of my job, I wind up sending a decent amount of stuff via overnight delivery, though rarely by FedEx (we have a discount deal with UPS Overnight that makes it cheaper). Of course, the question comes up "how do I describe in letters how I'm sending it?" "Via Courier" makes it sound like hand delivery. "Via Overnight?" "Via Overnight Delivery?" Or do we just go with "Via FedEx" in the vein of Southern "I'll have a coke." "What kind of coke?" "A Sprite."?
