Today I learned that: No Word Rhymes With Angel

I visit http://dictionary.com often. The front page of the site always has a quiz question or something to stimulate thought.

Today, the question was, "This common word does not have a rhyme."

And the answer is ANGEL.

There are words that come close...like wrangle... wrangle. (As in, to wrangle a horse.)

Yes, angel has a soft g and wrangle has a hard g, but it still comes close enough, I would think for lyricists or limerick writers.
