The word contains the letter 'e' and has 6 letters. The most common letters in the English language are 'e', 'a', 'o', 't', 'i', 'n', 's', 'h', 'r', 'd'. Since I've already guessed 'a', 'e', 'n', 'o', 'r', 't', my next guess will be a commonly used letter that hasn't been guessed yet, such as 'i' or 's' or 'h' or 'd'. I'll choose 'i'
