Backtranslation: his ally
If you often order translations into languages not dominating, it is possible, many times, have doubts about the quality of the product that are giving. Is it a good translation? It really reflected what the original text says? Does it have the same style? A good way to find out is to check with someone who knows the language. But if you don't know anyone, there is something that can help you: the inverse translation.
