Always double the last consonant of a word when adding -ing.

Question

Quizplus · Accepted Answer

Doubling the last consonant before adding -ing depends on the stress pattern of the word and whether the last syllable is stressed. If the base word is a single syllable or ends in a single vowel followed by a single consonant and the last syllable is stressed, then you double the consonant (e.g., "run" becomes "running"). However, if the last syllable is not stressed or if the word ends in two consonants or a vowel, you do not double the last consonant (e.g., "visit" becomes "visiting", not "visitting").
