The difference between regular and irregular verbs lies in how they form their past tense and past participle.

• Regular Verbs: They follow a predictable pattern, typically adding “-ed” to the base form to create the past tense and past participle. For example, “walk” becomes “walked” in both past tense and past participle.

• Irregular Verbs: They do not follow a consistent pattern and often have unique past tense and past participle forms that must be memorized. For instance, “go” becomes “went” in the past tense and “gone” in the past participle.
