Spelling Rule: Changing a word like SAD to SADDER, or SADDEST is called adding a suffix. When it's a syllable with a short vowel, you may have to double the consonant before adding the suffix.
This is one of 20 songs imbedded in our educational spelling software, Wordy Qwerty, that teaches 2nd to 4th graders how words are built in English. The songs help children remember important spelling rules. You can also purchase and download the songs in iTunes, under the title "JingleSpells: Songs to Spell By".
