Trivia - Insignificant or inessential matters
There are several theories associated with the origin of the word. The strongest contender being :
In early Latin, tri =three, and via = road. Hence, Trivium meant "the meeting place of three roads, especially as a place of public resort." In the Roman empire, a trivium would often have a tavern and such a place was viewed as common and vulgar. Latin adjective triviālis, derived from trivium, thus meant "appropriate to the street corner, commonplace, vulgar."
The first known usage of the word "trivial" is from 1589; it was used with a sense identical to that of triviālis. Shortly after that trivial is recorded in the sense : "of little importance or significance." Gradually, the word trivia came to be applied for any information that is of fleeting importance and of general interest.
Trivia on Trivia :
1)The word was popularized in its current meaning (information of the kind useful almost exclusively for answering quiz questions) in the 1960s by two of Columbia University students, who created the earliest inter-collegiate quizzes that tested culturally important and unimportant facts, which they dubbed "trivia contests".
2) National Trivia Day is celebrated on January 4 in the United States. The origins of the holiday are unknown. Many observe the holiday by playing games of knowledge and/or by sending an email or making a phone call to impart a quick little-known fact to friends and family.
