How does the CVC Doubling Rule impact spelling?

The CVC Doubling Rule significantly impacts spelling by requiring the doubling of consonants before adding a suffix when certain conditions are met. This rule typically applies to one-syllable words ending in a consonant following a single vowel, which is then followed by a suffix that starts with a vowel. For instance, in the word "run," when adding the suffix "-ing," the rule dictates that the final consonant is doubled, resulting in "running." This doubling helps maintain the short vowel sound in the base word before the suffix is added. Understanding this rule helps students correctly spell words and recognize the importance of syllable structures in the English language.
