Regular Verbs: The Rule Followers

Most verbs are good citizens. They follow the rules! To talk about the past, we simply add 'ED' to the base form.

Investigate + ed = Investigated

Look + ed = Looked

Spelling Rules Clues

1. Only add D

Ends in E: Just add D (Close → Closed)

2. Y becomes IED

Ends in Conosonant + Y: Change Y to IED (Cry → Cried)

3. Double Trouble

Short vowel + Consonant: Double the last letter (Stop → Stopped)

Irregular Verbs: The Rule Breakers!

Some verbs don't follow the law. They change their appearance completely to hide from the detective! You must memorize their disguises.
