What I find quite interesting is in the northern irish dialect, plural you is quite uncommon, usually plural you becomes yous or yousins, because irish has seperate words for singular and plural you
I wonder if the 20th century NYC dialect had "yous" from the wave of irish immigrants. As in "Yous guys ova hee". (Speaking as a native new yorker who doesn't hear this dialect much anymore except for maybe at a mechanic in, say, south brooklyn)
