Past Tense vs. Past Participle
Some people confuse the past tense with the past participle. Usually, they will use the past participle instead of the correct past tense. You will hear some people say I seen it, when they should say I saw it. Or they will use the past tense instead of the correct past participle: We could have went to the movie.
Cold chills run up the spines of listeners who are grammatically aware.
