Thank you, Laurent_R. If it is the case that grep outputs the values themselves that are true, how is it that the  next unless grep !/(.).*\1/, @list;line appears to be doing what I want it to in this:
for (sort keys %words) { my @list = sort @{$words{$_}}; next unless @list > 1; next unless grep !/(.).*\1/, @list; print "@list\n";
If grep outputs the words themselves, why is the "next unless" part working?
