Spelling Rule 17

Rule 17 refers to when we double the letters, f, s, z and l. It is also known as the FSZL Gang Rule. We often double ‘f’, ‘s’, ‘z’ and ‘l’ if they come after a single vowel at the end of a one syllable word. For example: will, off and fuzz.

This rule sometimes applies to two syllable words such as recess.

• For example: off, miss, buzz, will.

Special Note:

Not all words will follow the spelling rule. These are called exceptions. If 90% or more words follow this rule then this is still a great tool to help become a proficient speller. Language experience will deal with the rest.
