Then I copy the translation, and put it through the Altavista Translator again. Then I do it again, using French. And maybe again. And I read. The inadequecies of the translation process give me a host of synonyms and a completely new sentence structure to play around with.
Word choices are unusual and often very evocative.
Most importantly, it's fresh. But I keep doing it. I like playing with toys. When creating dialogue for say, a Spaniard who speaks in broken English, for true authenticity a writer should understand how sentence structures are formed in Spanish. Technically, the Translator should be useless in this respect.
