Thank you. 1,000 times over, thank you.
I learned this fact in my high school Latin class, over 40 years ago. My teacher had started a daily routine where we learned 2 new vocabulary words every day, as well as the etymology of those words. It was supposed to help us with the SAT scores, but I only got a 740. On Verbal.
Anyhow, SHE told us that pusillanimous is what gave rise to "*****" as an insulting word to describe someone's cowardice and lack of toughness.
And this is why I love using the word. People think I'm trying to be vulgar, when I'm really paying tribute to the word pusillanimous.
