Latin is a language that was originally the chief language of the Roman Empire. While it shares many etymological similarities with ancient Greek, it is a much more rigidly-structured language as a result of the more military nature of Roman society. Citizens of Rome (both native and naturalized) were expected to speak Latin; not to was a sign of barbarism. Nowadays, other than linguists, the only major two groups that use Latin are the Catholic Church and scientists (usually biologists). Unfortunately, this has given Latin an unfair image as a language of stuffy intellectuals. This is compounded by the fact that most Latin education programs teach the G-rated version of Latin (i.e. the version without any curses or real Roman history), despite the fact that Latin contains some awesome curses. Some of those are included below.
