Letterhead → It is formed from "letter" (from Old English *lettera*, meaning a written character or symbol) and "head" (from Old English *heafod*, meaning the top or beginning). The term "letterhead" refers to the heading at the top of a letter, typically containing the name and address of the sender.
Think of the 'written character' ('letter') at the 'top' ('head') of a document — that's what a letterhead is.
