So are words like vernier and hovercraft. But if I tried to apply them to pregnancy, everybody (except you) would be confused. It was pointed out to W4U that he is misusing words, and thus not making sense. Instead of simply correcting it, he just keeps at it - insisting, despite his own dictionary reference to the contrary, that he's right. So this is not a conversation. Unless someone chimes in with a sensical viewpoint, this thread is going nowhere. Vernier a nice hovercraft, W4U!
