Decipher a Coded Message
  • Find your first letters by looking for the one-letter words, "A" and "I." (If the letter is capitalized and in the middle of a sentence, it's probably an "I.")

  • Look for a three-letter combination that repeats throughout the message. Chances are this word is "the."

  • A single letter that comes after an apostrophe is probably an "s" or a "t."

  • If you're still stuck, try to figure out some of the two-letter words (as, at, if, it, is, of, to, etc.).
