This was a pronunciation error that I myself was totally unaware of until just a few years ago. To most English speakers, the * symbol is called an asterick. Notice that I spelled it without an s because that is exactly how many people pronounce it. For some reason, the little s sound is too difficult to pronounce, so it is simply omitted altogether. It is not a silent sound, however. Remember to say it with the s sound. (Listen)
I am bare impressed with the article I have just read. I wish the writer of http://www.grammarerrors.com can continue to provide so much worthwhile information and unforgettable experience to http://www.grammarerrors.com readers. There is not much to tell except the following universal truth: The truth is out there. Way far out there. I will be back.
