On Valentine’s Day, hearts are everywhere. Candy hearts. Heart emoji. Every imaginable sort of heart-shaped chocolate, greeting card, decorative banner, bric-a-brac. Hearts even swell in our words – and not just the likes sweetheart or, depending on how feel about the holiday, heartsick. I grant you no quarry, you discordant, incredulous, myocardial miscreant! Yes, these words also have the word “heart” at their etymological heart.
