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.
Begging the question
The phrase "begging the question" originated in the 16th century as a mistranslation of the Latin "," which actually translates to "assuming the initial point". In modern vernacular usage, "begging the question" is often used to mean "raising the question" or "dodging the question". In contexts that demand strict adherence to a technical definition of the term, many consider these usages incorrect.
