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.
Buzzword
The origin of buzzwords can be seen in as coming from business students studying at Harvard University as a way to help them gain better results from their studies. Such language terms were collated and then became what is known today as "buzzwords". During the early years of buzzwords, buzzwords were used by students as a means to enable them to quickly recall items of importance. As an example, "If his analysis does not highlight the most important problems he has 'poor focus', and if he fails to emphasize important recommendations he will be accused of 'tinkering'. If the sequence for the 'implementation' of the recommendations is not good it is a matter of 'poor timing'. To succeed, the student must 'get on top of the problem'. He must 'hit the problem' and not 'shadow box' it. If he cannot do these things he might just as well 'turn in his suit'".
