Etymology: The machine came first, and the name came from a cylinder. Medieval Latin "calendra" was a corruption of Latin "cylindrus" (cylinder), itself borrowed from Greek "kylindros," and it passed into Middle French as "calandre." The word was the name of a roller press, and the English verb for pressing cloth or paper between rollers grew out of that machine name. The "calender" spelling was adopted in the 17th century to keep the machine apart from "calendar," the system for reckoning days and months, even though the two words have entirely different origins. The machine's older connection runs in a different direction too. Through Middle French "calandrer" and Middle English "calendren," the verb was tied to the practice of smoothing and glossing cloth, and the same root-family gave English both "cylinder" and "calander," a doublet that kept the sound of the original closer to its source.
