Which spelling rule involves doubling a letter?

The FLOSS Rule pertains to the process of doubling a consonant in specific contexts when it comes to spelling. This rule is typically applied to one-syllable words that end in a short vowel followed by a single consonant. For instance, in the case of the word "stop," when adding a suffix that begins with a vowel, such as "-ing," the final consonant is doubled to form "stopping." This vehicle of understanding helps students grasp the concept of when modifications to the spelling are necessary based on the structure of the word and the phonetic spelling rules in play.

In contrast, the Changing Rule, Dropping Rule, and Network Rule do not specifically address the doubling of letters. The Changing Rule focuses on altering the base of certain words when adding prefixes or suffixes, while the Dropping Rule typically involves removing a final 'e' before adding a suffix that begins with a vowel, and the Network Rule relates to understanding connections between words rather than specific spelling modifications. The context provided by the FLOSS Rule is crucial for developing appropriate spelling skills in students, as it aids in recognizing patterns that lead to correct spelling in various linguistic situations.
