Adding -ing Rules


Just Add Rule:


When adding a suffix to a root/base word, write the root/base word and add the suffix.


Examples: helping, handed watch + -ing watching watch + -ed watched happen + -ing happening happen + -ed happened


Doubling Rule – Part 1: In a one-syllable word, with one short vowel ending in one consonant, double the final consonant before a suffix starting with a vowel. Examples: batting, batted stop + -ing stopping stop + -ed stopped rob + -ing robbing rob + -ed robbed slip + -ing slipping slip + -ed slipped


Words ending in Silent e: When a root/base word ends with final-e, drop-e before a suffix starting with a vowel. Examples: escape + -ing, = escaping ignite + -ed = ignited dance + -ing dancing dance + -ed danced notice + -ing noticing notice + -ed noticed


Words ending in y: When a root/base word ends with –y change the y to i if there is a consonant before the y except if the suffix begins with an i. Keep the y if it is part of a vowel team. Examples: carry + -ing = carrying, enjoy + -ed = enjoyed, fly + -ing = flying study + -ing studying study + -ed studied dry + -ing drying dry + -ed dried hurry + -ing hurrying hurry + -ed hurried
