How good is your grammar?

On this page I am gathering all the "Do you know..." posts and anything I post related to writing or grammar.

Do you know...

#1  that titles of TV shows of half-an-hour or less are to be in quotations and hour-plus show titles are italicized instead?
example:  Do you like "Jeopardy" or "Wheel of Fortune?"  I loved Buffy the Vampire Slayer and Smallville.

#2  that the difference between "blond" and "blonde," other than the letter "e," is that "blond" is an adjective and "blonde" is a noun?
example:  As a toddler, my son has blond hair, but I expect it to darken as he grows.  I doubt he will still be a blonde when he is older.

#3  that "short term" is hyphenated when used as an adjective before a noun, and is not hyphenated when "short" describes "term" and "term" is a noun?
examples:  One of my short-term goals is to paint a little every day.  In the short term, I will go to the library every day.

#4  whether the spelling of the color of shadows is spelled "gray" or "grey?" 
The answer is that it is spelled both ways.  Americans prefer "gray" and Brits prefer "grey."  Does that mean "Fifty Shades..." is British?  Not necessarily; either spelling is acceptable.
