About the Word:
For a long time before megillah was the word that was used to refer to an overlong story or convoluted production its primary meaning was a considerably different one. The Megillah is typically read out loud from a scroll in course of certain Jewish holidays. At the beginning of the 20th century megillah began to be used in a figurative sense to refer to a long or complicated tale. It comes to English from the Yiddish word megile, which is itself from the Hebrew mĕgillāh, meaning 'scroll.'
Example:
"Yesterday I was sore on the whole Megillah down here; to-day you couldn't drive me away mit wild animals." New York Tribune, 25 Feb. 1914
