second-person pronouns redux

[P2052 at AOL.COM]

In Southern African-American communities, I often hear, "nem,"  an even
further reduction of "and them."  My guess is that the process was the
following:
"and them" > an' 'em > nem.  For example, a speaker might at some point have
uttered the following:  "Kathy and them left town."  Later, the utterance was
reduced to "Kathy an' 'em left town."  Now, it has become "Kathy 'nem left
town,"  the pattern which I hear almost all of the time.   PAT
