I feel like the Golden Dustman of "Our Mutual Friend", sifting through the jumbled detritus of the dictionary, with an eye for the oddly shaped, shiny item. In my haphazard searches, I have stumbled across a few remarkable words and phrases. Sometimes the simple fact that there is a word for something is surprising; or the word may suggest that it has a certain meaning while meaning something entirely different; in other cases, the etymology of the word is amusing.
Blue moon - I don't know why a blue moon is blue, although a factitious folk etymology would be easy to contrive, but the common definition of a blue moon is the second full moon in a month. This only happens occasionally, and occurs because if the moon is full on one of the first few days of the month, there's just enough time for it to go through all its phases, and become full again before the month is out. This doesn't happen that often, just...once in a blue moon.
The New York Times Sunday Magazine of 31 January 1999 claims that the specific use of the term "blue moon" to mean a month with two full moons was only coined in the early 1980's, by an unidentified NPR commentator!
The most recent riposte in the controversy showed up in the New York Times on 1 April 1999 (presumably not a hoax!). This claims that in fact the first occurrence was in a 1946 article in Sky and Telescope, which in turn relied on a mistaken reading of a 1937 Maine Farmer's Almanac. Apparently, the Almanac used the term "blue moon" when four full moons occurred in a season, defined as one of the periods between an equinox and a solstice (you know, technical winter, spring, summer and fall). Moreover, when four moons occurred in a season, it was the third moon that was called blue; this was because the Almanac had traditional names for the first, second, and last moons occurring in any quarter. An article correcting this error is supposed to have been printed in the March 1999 issue of Sky and Telescope.
The bird's eye lowdown on the caper is that, in fact, if you go with the older definition, 1999 does not have any blue moons, and the next one occurs in February 2000. As they say, everything you know is wrong!
Rovescio: a rovescio.Now what do you do? I was convinced I had found a classic recursively useless definition or CRUD, until I realized that perhaps this was an Italian phrase, a rovescio, and was able to find the real definition! By the way, my dictionary defines all the cardinal and ordinal numbers up to 100. I ran across definitions for "eighty-third: the eigthy-third item in a sequence...", and that sort of bunk.
