Slay is old English and shouldn't bee said in the modern world. this would be ridicules a we don't speak old English now do we? am I right to think I am righting in "modern English"? many people would think that slay is a relatively new word butt it is not. I believe Shakespeare used it. so should wee stopp? Answer: Yes.

People used SLAY to, simply, say die.

Funny.
