The Welsh Not or Welsh Note was a piece of wood, inscribed with the letters “WN”, that was hung round the necks of children who spoke Welsh in some schools in the 19th century. The “not” was given to any child overheard speaking Welsh, who would pass it to a different child if overheard speaking Welsh. By the end of the day, the wearer of the “not” would be given a lashing. The idea of the “not” was to discourage pupils from speaking Welsh, at a time when English was considered by some to be the only suitable medium of instruction.
