Things I Hate: A Series of Unfortunate Annoyances.
Part II. Grammar Police
“Really! I seen it!” You didn’t seen anything. That makes no sense. This is one of many grammar errors that I hear on a daily basis. For most of us, English is our first language, so let’s speak it!
“There are approximately 200 irregular verbs in the English language."
These verbs form the past and past participle (have + verb) tenses differently from the present. These irregularities can be a nagging source of confusion for many writers and speakers of English.” I agree, www.grammarerrors.com
The correct usage would be, “Really! I have seen it!” I know that sounds a little weird, but it’s correct, so use it. Thank you!
