To give this entry a little more weight, here's a lovely, nuanced Supernatural fic I just re-found. You all know me: I love stories, I love words and language, I love characters (I'm tempted to add "I love Dean"). This story has them all.
credo ut intelligam, by girl_wonder
Dean liked that when he said 'I fight' he didn't need to have a pronoun in Latin. He could use one word and that would mean that he was Dean and he was fighting. I fight. pugno.
Go forth and read, even if you're only vaguely familiar with the fandom, and it doesn't matter if you know anything about Latin (though my own Latin studies did endear this fic to me in a particular way).
