What is the origin of the question mark?
Question mark
Lynne Truss attributes an early form of the modern question mark in western language to Alcuin of York.[2] Truss describes the punctus interrogativus of the late 8th century as, "a lightning flash, striking from right to left".[3] (The punctuation system of Aelius Donatus, current through the Early Middle Ages, used only simple dots at various heights.)
Semicolon
In Greek and Church Slavonic, a semicolon indicates a question, similar to a Latin question mark. To indicate a long pause or separate sections, each with commas (the semicolon's purpose in English), Greek uses, but extremely rarely, the "άνω τελεία", an interpunct ( · ).
