Prophecies can be tricky. That's why I tend to avoid them.
But if you can't, then be sure to distinguish between prophecy and prophesy. What's the difference?
Prophecy is a noun–meaning a prediction of something to come–and is pronounced "see" at the end (it rhymes with "look at me").
Prophesy is a verb: to make a prediction. It's pronounced "sigh" at the end (rhymes with "my oh my").
Unfortunately, in a recent article I let slip by "prophesies" where "prophecies" was meant. A keen-eyed Italian reader called me–gingerly, and actually by email–on the mistake.
Mistakes will be made, but I prophesy that I won't let that slip by again. I hope that prophecy comes true.
In the meantime, I wish a very happy new year to all my readers.
