When did the word “sat” replace “seated” as used in this article? I see it all the time - “He was sat in the back row,” “We were sat by the hostess in a booth,” etc. He was seated on the toilet (or the back row), and the hostess seated you in a booth.
Probably the same time “hung” replaced “hanged”. Too much trouble to teach kids all the conjugations when we can simplify them and have more time for political indoctrination.
The English often have different ways of writing and speaking. I read that quite a bit though it does always looks odd.
