Oh dear Rufus, once more we disagree .
For those studying Romance languages, it definitely helps if you know some Latin.
Being familiar with Latin got me out of a few sticky moments, when I was stuck trying to translate some obscure text in an exam.
However, the best thing about learning Latin was it made it so easy for me to understand the grammatical structure of other languages.
Although my knowledge of my other languages needs a bit of a refresher course, the Latin vocabulary comes back with no difficulty at all. Good old fashioned rote learning, you can't beat it!.
Thank goodness, learning languages in school nowadays, is much more fun, from when I was young.
