    English Rules Learn how to spell the progressive (or continuous) form of verbs. As we have seen in the first article (ING-lish: Spelling the -ing Form of Verbs Correctly, Rule 1), forming continuous verbs is, unfortunately, not a simple matter of attaching -ing to the basic verb. These rules will help you to pick up on the "awkward" verbs and learn to spell these forms correctly.

    Rule 4: Double Consonants after Short Vowels

    In verbs ending with consonant + vowel + consonant, you should double the final consonant before adding -ing.


    • run - Hurry up! We're running out of time.
    • hop - She's hopping on one leg.
    • beg - I'm begging you to come home.
    • swim - Let's go swimming tomorrow.
    • ship - The marines are shipping out next week.

    Note also the doubling in the verb put, even though the vowel is not short:

    • put - Isn't that sweet? He's putting his arm around his mother.

    QU as a Consonant

    Verbs ending with qu + vowel + consonant follow the same rule. This is because the u is acting for the consonant sound /w/ in the verb.


    • quit - He says he's quitting his job next month.
    • equip - The coach is equipping the team with a new strip.
    • squat - We found them squatting behind the bushes.

    1. Verbs of more than one syllable do not double the consonant if the stress is not on the final syllable.

    • admit: The stress is on the final syllable, so we double the consonant. After admitting to the crime, the man was taken into custody.
    • visit: The stress is on the first syllable, so the consonant is not doubled. She's visiting her aunt on Sunday.

    2. The letters h,w, x and y are never doubled.

    • fix - She's fixing her broken stereo.
    • paw - The mad dog was pawing the ground.
    • watch - I'm watching you!
    • say - What are you saying?
