Wipe That Silly Chagrin Off Your Face!

 I had always calmly assumed chagrin meant about the same as regret.  The ethno-poem yesterday snagged my attention with the word.  So, it turns out that there is also a large element of embarrassment to it.  It has to do with regret at failure.

According to Vocabulary.com it comes from a French word of the same spelling having to do with "melancholy, anxiety and depression".  One funny thing is that it has been thought to be related to an English word, shagreen, for rough untanned leather.

False etymologies are one of my favorites and fun for another time.  They spring up like mushrooms after a reign!
