To Trick The Eye
Here's a new word for you to learn. Actually it comes from French. Trompe l'oeil. It is now part of the English language. It means "to trick the eye". Now the problem is how to pronounce this word. Since it came from French, it should be pronounced in the French way. However, most English speakers find difficulty in pronouncing the two words in l'oeil. So it becomes much simpler and easier on the tongue. In US English, it is pronounced something like "tromp loy" and in British English, it sounds something like, "trom ploy".
