Types of Changes in Irregular Verbs:

Common Patterns:

• Irregular verbs often show a pattern, such as:
  • Verbs ending with “-ing” in the present tense often change the vowel in the past (e.g., sing ➔ sang).
  • Verbs ending with “-d” in the present may drop the “d” and add a different ending in the past (e.g., build ➔ built).
