So then the word “artificial” is a stone to you because you don’t know how to use it?

I’m going to simply assume that since you are a language teacher that maybe English isn’t your first language but maybe a second or third. Good for you for teaching languages but in this case you should double check your own work.

Please take the time to look up the word “artificial” in an English dictionary. You’ll then understand why I’m telling you that you sound foolish when you use it the way you have been. Again I’m not trying to hurt your feelings but you are using the word very incorrectly. It does not help that it is in the first sentence of your article. It does not mean whatever you think it means.

And again not derogatory toward you, just to your choice of words. Which as a writer you are responsible for.
