Irregular Verbs
* Rule: Irregular verbs have no consistent rule for forming the past tense. They have unique forms that must be memorized.

* go - went
* see - saw
* eat - ate
* have - had
* do - did
Key Points to Remember:
* Spelling: The "-ed" ending for regular verbs may need to be adjusted for spelling.
* Double the final consonant: If the base word ends in a consonant followed by a single vowel, double the final consonant before adding "-ed". (e.g., stop - stopped)
* Change "y" to "i" before adding "-ed": If the base word ends in a consonant followed by "y", change the "y" to "i" before adding "-ed". (e.g., study - studied)
* Memorization: You need to memorize the past tense forms of irregular verbs. There are lists and resources available online and in grammar books.
