Best practice
When using "seen" as the past participle of "see", ensure it is paired with an auxiliary verb such as "have", "has", "had", "was", or "were" to form perfect tenses or passive voice constructions.
Common error
Avoid using "seen" as the simple past tense of "see". The correct form is "saw". For example, use "I saw the movie" instead of "I seen the movie".
