Here's how it works:
* Identify the base word: Look at the word before the suffix is added.
* Check for a single consonant: The base word should end in a single consonant.
* Check for a single vowel: The consonant should be preceded by a single vowel.
* Check the stress: The stress should fall on the last syllable of the base word.
If all these conditions are met, double the final consonant before adding the suffix.
Example:
* Base word: "hop" (single consonant "p" preceded by single vowel "o", stress on last syllable)
* Suffix: "-ing"
* Result: "hopping" (double the "p")
Exceptions:
* Words ending in "w" or "x" do not double the consonant.
* The double consonant rule does not apply to words ending in "c" followed by "k".
