Question mark
In the early 13th century, when the growth of communities of scholars (universities) in Paris and other major cities led to an expansion and streamlining of the book-production trade, punctuation was rationalized by assigning Alcuin's stroke-over-dot specifically to interrogatives; by this time the stroke was more sharply curved and can easily be recognized as the modern question mark.
Irish question
The Irish Question was a phrase used mainly by members of the British ruling classes from the early 19th century until the 1920s. It was used to describe Irish nationalism and the calls for Irish independence.
