This link made the rounds last week from The Oatmeal, as a guide to ten frequently misspelled words. Grammarians are generally a disliked bunch, because they can be very grumpy about commas, contractions, and the big mother of bugaboos, spelling. This guide (which you can buy as a poster) uses graphics and font to create an entertaining reminder that “it’s” means “it is” or “it has,” while “its” is a creature, you know, like the Christmas leftovers in the back of your refrigerator. Evidently, a lot of people misspell “weird” as “wierd,” which is, well, weird, but Oatmeal uses a fun device to keep violators on track: spell it wrong, and you kill a dolphin, for which the creators provide a graphic.
So please, save the dolphins.
