He was sat
Is the dialect expression “He was sat ...” in place of “He was sitting ...”, which is quite common in the UK, also found in US English? When I first arrived in England I was astonished to hear a teacher tell his class to “stay sat” when they had done whatever it was they were doing. Now it is like an epidemic, heard on the radio and television too, used by people speaking otherwise standard English. US dialect is very rich and diverting, but I wonder if this one features?
