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.
Wondermark
In 2014, the word "sea lioning" (also rendered "sea-lioning" or "sealioning") was coined based on a "Wondermark" strip, referring to a type of Internet trolling which consists of bad-faith requests for evidence, or repeated questions, in an attempt to derail a discussion or to wear down the patience of one's opponent. In the comic strip, a character expresses a dislike of sea lions, and a sea lion immediately appears, following the character around to repeatedly ask why that is.
