The Spelling Rules for Adding Suffixes:

The Doubling Rule

The doubling rule is only needed for vowel suffixes.

If you are adding a vowel suffix to a short vowel word that ends with a vowel followed by one consonant (VC), you double the consonant.

 Listen to these examples:
  Right Wrong
stop + ed stopped stoped
dig + ing digging diging
fat + er fatter fater
