What Is the Double Consonant Rule?
The rule states: When adding a suffix beginning with a vowel (‑ing, ‑ed, ‑er, ‑est), double the final consonant if the word ends in a single consonant preceded by a single short vowel, and the final syllable is stressed.
Rules with Examples
| Rule | Example | Explanation |
|---|---|---|
| One‑syllable word, short vowel + consonant | hop → hopped, run → running | Double consonant |
| Multi‑syllable word, stressed final syllable | begin → beginning, prefer → preferred | Double consonant |
| Multi‑syllable word, unstressed final syllable | open → opened, visit → visited | Do not double |
| Words ending in vowel + consonant + e | hope → hoping, make → making | Drop “e,” don’t double |
| Words ending in “w, x, y” | snow → snowing, fix → fixed | Do not double |
📌 Common Exceptions
- Travel (UK vs US): UK → traveller, US → traveler
- Focus: focused not focussed (though both appear)
- Benefit: benefited not benefitted
