I think I'll clear up a couple of issues for the world ... or I would, if the world read my blog.
Listen up, world! If you mean voilà!, as in French for "See there!", please say so. Please, please do not say "viola!", which is either 1) a musical instrument or 2) a flower or 3) an old-fashioned first name. Seriously—I have studied several languages at the alphabet level, and have never yet run across one in which the vowel combination "io" makes the sound "wah."
Similarly, "I before E except after C and when sounding like A as in neighbor or weigh (and on weekends and holidays and all throughout May ... Brian Regan, you rock)—and in the word 'weird!' " According to The Oatmeal, every time anyone spells it "wierd," a dolphin gets run over by a jet ski. Think of the dolphins!
The Oatmeal covered a lot of other common spelling errors in the above link. That piece is a little crass in places (okay, it's a lot crass all the way through—sorry about that), but by the end it's definitely harder to forget that there is no A in "definitely."
