The London Review of Books has a nice piece by Lynn Visson, a former UN translator, on the secrets of her trade:
The most important language in most international organisations has no name: it is the institution’s own bureaucratese, its linguistic Esperanto. We never do something, we implement. We don’t repeat, we reiterate and underscore. We are never happy, we are gratified or satisfied. You are never doing a great job: you are performing your duties in the outstanding manner in which you have always discharged them. There is not heft or embezzlement, but rather failure to ensure compliance with proper accounting and auditing procedures in the handling of financial resources. This is a language the interpreter must master very early on.
But sometimes there are surprises…
Some colleagues play tic-tac-toe with each other out of sheer boredom. Delegates too sometimes get bored. Instead of beginning his speech with the usual ‘Thank you, Mr Chairman,’ a Russian delegate for whom I was interpreting launched in with ‘O my lost youth, my lost youth,’ and proceeded to reminisce about the mosaics in the main cathedral in Sofia, including one figure in the cupola that reminded him, as he put it, of ‘Christ in a space suit’. Several delegates turned towards the English booth with puzzled looks, undoubtedly wondering if I had gone mad.
…and sometimes things go horribly wrong:
One unfortunate freelancer announced to an entire room that a Spanish speech he had just finished translating was ‘the stupidest and most boring speech I have ever interpreted in my entire life’. I doubt that he was ever hired again.
