Explanation:

- Past Participle: For regular verbs, the past participle is formed by adding "-ed" (e.g., "seen," "eaten"). For irregular verbs, it varies (e.g., "been," "swum").
- Auxiliary Verb: Use "have" for plural subjects and "has" for singular subjects.
- Negatives: Add "not" after the auxiliary verb.
- Questions: Start with the auxiliary verb ("Have/Has") followed by the subject and the past participle.
