It is No Tragedy, a Short Lexicon Lesson

Everyday on the television news the news journalists use the word tragedy and they are killing the word.  In fact they use it so much I don’t really know what they mean by it.  A tragedy refers to a preventable event caused by hubris and or by fate as I learned though literature classes.  A news journalist does not know enough personal information about person’s life to know this. 
Even dictionary.com doesn't get to what is probably the newscaster’s definition of the word until the 5^th and 6^th entry.  Dictionary.com is written by word people though, so they understand these things.  I could never be a news journalist probably for this reason.  I’d prefer to say horrible ordeal.
