Dear D___:

“Got” is the standard past participle in the UK. “Gotten” is standard in North America. Most authorities accept both. In colloquial speech, “got” often does take the place of “have” as you pointed out. I would certainly avoid this in any kind of formal speech, but when I see a Pennsylvania license plate, I think of that old James Taylor song, “You’ve Got a Friend.” It might not be good formal English, but they probably chose the slogan for the “warm fuzzies” that people might get thinking of that song.

Basically, we did not address the use of irregular verbs except when they
were spelling problems. We felt that most native speakers were comfortable with them, and most non-native speakers had charts or books directed for their needs.
