mike11111, I should have made clear that my last post referred to jomifl not you. As I acknowledged, you corrected an error that no doubt could only originate from a translation engine.
Nevertheless, I am curious as to what you mean by your "own knowledge"? What knowledge of the Welsh language do you have? If you're fluent in the language, why not disclose the fact?
As far as your final sentence is concerned, I think you need to research a little further regarding the Khymer Rouge. However, leaving that to one side, I'm afraid that someone who cannot understand any language they wish to converse or write in is best advised not to use it. Whilst everyone makes mistakes during formal learning of a language, it is important to realise that translation engines cannot provide a grammatically correct short-cut for those that have no desire to do so. Those that insist upon using such a facility, can expect criticism and/or correction from native speakers when they get it wrong. Jomifl got it wrong. That's it pure and simple.
