OK, this is kind of a stretch, but the author of Word A Day starts out with the story of his daughter’s bracesa and rumination on the origin of the term ortho, which he believes “derives from Greek and means lots and lots of money.”
noun: 1. The commonly accepted way of spelling words. 2. The branch of knowledge concerned with the study of spelling and representing sounds of a language by letters and diacritics.
Via French and Latin from Greek ortho- (correct, right, straight) + -graphy (writing).
