Question mark
The rhetorical question mark or percontation point was invented by Henry Denham in the 1580s and was used at the end of a rhetorical question; however, its use died out in the 17th century. It was later revived in modern-day society by Matt DiRoberto. It was the reverse of an ordinary question mark, so that instead of the main opening pointing back into the sentence, it opened away from it. This character can be represented using the reversed question mark (⸮) found in Unicode as U+2E2E. The percontation point is analogous to the irony mark, but those are even more rarely seen.
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'".
