When I type an i, why does it show up as an ia?

Well, since your problem has been solved…maybe someone can tell me why a get a ? Before so many words I type into my Mac iPad mini. It’s making me crazy. I tried googling to no avail. It can’t just be me!

Your computer’s probably just summoning the Black Goat of the Woods With a Thousand Young, I wouldn’t worry about it.

ETA: oh hey, ninjad by Half Man Half Wit.

Still, good an opportunity as any to mention my current reading material.
