It saddened me to find that in a Wiki article's history the word "juxtaposition" was once removed, because it had, apparently, confused an editor. He complained that it was "jibberish [sic]" and that he could not read the article "clearly" until he had changed it into "something clear." He stated that he "did not like big words" and also that he had not attended any high school English classes.

To put it another way ... "juxtaposition" had him flummoxed.

(Do you know what word I love, though? Backronym. Hallelujah!)
