I have to say that I've really got used to negative chunk expressions.
At first it looks a little strange, placing a minus before a number as
part of a chunk, but when you very quickly get used to it and then it
makes perfect sense. -1 is the last word, -2 the second last, etc. It
quickly becomes natural.
I'm not sure your example is very clear:
put word 2 to 5 from last of "a b c d e f g"
Does this give you "b c" or "c d e f"?
