Question

Which rule helps to indicate the spelling of the word "reoccur" when changing it to the word reoccurring. When adding a suffix that begins with a vowel to a root word that ends with a consonant, double the consonant before adding the suffix. When adding a suffix to the end of a word, always double the last letter of the root word before adding the suffix. "Reoccurring" is the exception to spelling rules and the spelling of this word must simply be memorized. To change the word reoccur to reoccurring, simply add the suffix "ring".

Answer 1

The correct answer is the first option: "When adding a suffix that begins with a vowel to a root word that ends with a consonant, double the consonant before adding the suffix."

Explanation: this rule is done with monosyllabic words which have a vowel followed by a consonant at the end of the root word. It also applies to root words with the same characteristics mentioned above, but which have more than one syllable and the last syllable carries the main stress.

Examples:

Monosyllabic words            Multisyllabic words with stress in the last syllable                                                                                                  

Fur > Furry                                            Prefer > Preferred

Blur > Blurred                                       Occur > Occurring
