How to translate "de-"? I was reading this article in The Guardian recently when I came across this sentence:


  By the time I have finished typing, Chris could have lost a battle of wits with the A358, or de-invented trains.


I was wondering how de-invented trains would be translated into Chinese.



21st Century English-Chinese Dictionary gives the following for -de


  “非…”,“反…”：
  
  decreation
  非创造 
  
  denormalization
  非标准化；非正常化  


I really don't think any speaker of Chinese is going to understand 非创造, in general, let alone as decreation.

非发明 -or- 反发明 is certainly not going to be a good translation of de-invent(ed).

But I'm not sure how it would be expressed at all.

Any ideas?
This is one of those cases where the flexibility of English to simply invent words that are intelligible makes the translation job a lot harder. Thus, there's probably no good answer because it will be a case-by-case basis.

Because de- has a plethora of meanings, there will be a plethora of translations. For de- in the sense of "removal," like "de-caffinated," 去 will likely be used (去咖啡因). In the sense of separation or division，like delamination，you might see 分 (分层). 
Because de- is a latin suffix, it shows up more frequently in scientific or technical words that might have their own way to be expressed in Chinese, such as de-emphasize = 淡化.
