  • “go” → “went”

3. Forming the Past Participle

• For regular verbs, the past participle is the same as the past tense: -ed.
• Examples:
  • “play” → “played”
  • “walk” → “walked”
• For irregular verbs, the past participle can be different from both the base and past tense forms.
• Examples:
  • “go” → “gone”
  • “see” → “seen”
