In the Late Middle English period, the shape of the English letter þ (thorn), which was derived from the Runic alphabet, evolved in some handwritten and blackletter texts to resemble the Latin letter y. The þ shape survived into the era of printing presses only as far as the press of William Caxton. In later publications, thorn was represented by "y", or by ẏ to distinguish thorn from y. By the end of the Early Modern English period, thorn had been completely replaced in contemporary usage by the digraph "th" (reviving a practice from early Old English), and the overdot was no longer needed outside of printings of very old texts. The overdot is missing from the only surviving usage of a Y-shaped thorn, in the archaic stock phrase ye olde (from "þe olde", pronounced "the old", but "ye olde" is often misanalyzed and pronounced with the modern "y" sound).
