Common Mistakes: When to double ending consonants when adding suffixes (by Carla)

Hello everyone!


Today we are going to have a look at another common mistake. We are going to review the spelling rules behind adding a double consonant when adding suffixes. It sounds very complex, but let me show you what I mean with an example: "run" --> "running".


SPELLING RULES


Monosyllabic Words (One Syllable)


In order to double the consonant when adding a suffix, the words need to follow 3 rules:

1. Composed of a single syllable

2. Only have a single vowel (vocal)

3. End in a simple consonant letter (e.g. P, T, N, G)


Quit --> Quitter, Quitting


Sit --> Sitting, Sitter


Fat --> Fatter, Fatty


Flat --> Flatter, Flattening


Log --> Logging, Logged


Run --> Runner, Running


Stop --> Stopped, Stopper


*If the words do not follow the three rules above, the consonant is not doubled. Therefore, if the word has more than one vowel, if it ends in a vowel, or if it ends with two different consonants, you would NOT double the last consonant when you add a suffix.


Feed --> Feeding, Feeder


Sleep --> Sleepless, Sleeper


Love --> Lover, Loved


Move --> Moved, Mover


Calm --> Calmed, Calming, Calmer


**You NEVER double the last consonant if the last letter is W, X or Y (even if it follows the three rules above).


Bow --> Bowing


Snow --> Snowing


Box --> Boxer, Boxing


Fix --> Fixed, Fixing, Fixer


Joy --> Joyful, Joyless


Play --> Playful, Playing



Words with 2 or More Syllables


Words with two or three syllables that end with a vowel followed by a consonant ONLY double that consonant if the stress is placed on that last syllable.


Begin --> Beginning, Beginner (the stress of this word is on "-GIN")


Prefer --> Preferred, Preferring (the stress of this word is on "-FER")


Regret --> Regretting, Regretted (the stress of this word is on "-GRET")


Occur --> Occurred, Occurrence (the stress of this word is on "-CCUR")



* Please bear in mind that if the stress is not placed on the last syllable, the last consonant is NOT doubled. Not even if the stress of syllables changes when you add the suffix.


Refer --> Reference, Referee


Offer --> Offering, Offered


Answer --> Answered, Answering



Words ending with VOWEL + L


Words ending with a vowel + L always double the last L when adding suffixes. This also applies to words that end with two vowels + L that are pronounced in separate syllables.


Quarrel --> Quarrelled, Quarrelling


Repel --> Repelled, Repellent, Repelling


Label --> Labelling


Fuel --> Fuelled, Refuelled


Duel --> Duelling



Exceptions


As always, there are certain exceptions that do not follow these rules. Nevertheless, these words are rare; so, you only need to learn to identify them and how to write them properly. Think of them as extra vocabulary :)


For example: Worship --> Worshippers, Worshipping


-------------


I hope you have found this post to be useful! So, please, never write "stopped" again with a single P!


Best wishes,

Carla
