gif_book121 Bonus Letters, the Fizzle, Floss, or Flossy Rule …all common names for this rule.

Another helpful spelling rule is:

If a one-syllable word ends in a short vowel and is immediately followed by the consonants f, l, s, or z, double the consonant.

Examples are:

  • fluff, puff, whiff, off, buff
  • bill, hill, hall, mull, fill, tall
  • mass, kiss, chess, less
  • jazz, buzz, fuzz

(The letter /a/ does not always have the expected short sound.)

Remember, these rules are very helpful for students with specific learning disabilities in making sense of spelling and reading.
