Some of the rules may be confusing, but there will be examples to guide you. We will break that down. Those words do not follow this rule, so you will not double their final consonants when you add a suffix. Syllables added to the end of a word to change or modify the meaning of the original word. For this rule, only the suffixes ed, er, ing, ance, or fit the description by beginning with a vowel.
Lets see how it works.
AND if the final syllable is the accented, or stressed, syllable. Keep the E when the suffix begins with a consonant. This rule is explained on the More Rules page. When there is a consonant before the Y, change the y to i and add the suffix. We will just give a brief summary and a few examples of the major rules.
