Latin; a dead language with no practical applications except perhaps the deciphering of old texts and as a particularly quaint party trick.
Thankfully, as Harry finds out, Latin is not as dead as he was first taught when he decided to learn the language. It wouldn't have mattered anyway, of course; he loved Latin, and would have been proud to know it even had it been as useless as it was pretty. But in the world of Wizards, the world of Magic, Harry realizes his rare talent with words is particularly valuable in the highly complicated and controversial subject of Spell Creation, a subject he soon becomes enamored with despite having to hide his interest from everyone.
Besides, it's not like he's going Dark, after all.
