The following words do not contain the letter "R", contrary to popular usage: 
  • Oil
  • Wash
  • Alpha/delta (no offense, Asians)
I'm taking a class where the professor mentions Euler angles on a regular basis.  I've heard it pronounced "oiler" and "yooler" but haven't heard a definitive answer as to which is correct.  But one thing I know for sure is that "erler", which is how the professor says it, is 100% wrong. #language
