I think I see your point.
Out of fun, I used the Google translator to translate each of the three into Polish:
- Byłem parkowania na parkingu.
- Zatrzymałem samochód na przystanku dziedzinie samochodów.
- Zaparkowałem samochód na parkingu.
2 is very wierd. I wouldn’t rule 3) out but I trust 1) more, simply because it’s less removed from the original.
My concept of “having a life of its own” assumed that phrase in language A translated into phrase in language B and B becomes the basis of C, D, E, etc. In this case if B for whatever reason gets changed, then C, D, E, etc need to be changed. It would have been totally different had A been translated to B, C, D, E, etc separately.
ICEL translations, whether they were good or not, were apparently used to translate into other languages. Now all those other languages need to be retranslated. Had each of those languages been translated from the Latin, then the extent of the corrections would not have been so severe. Using your Chinese phrase, theoretically you retain more of the meaning if you translate directly into English (regardless of quality) or Polish or Spanish or Italian, rather than translating into English, then using the English translation to go to Polish, then using the Polish translation to go to Spanish and then Italian. For all we know, the Italian-speaker might end up understanding the phrase to mean that he was stopped in the parking lot because the car stopped or something like that.
