Excuse my bluntness, but I utterly fail to make sense of this. Reformulating your understanding of it would surely be beneficial.

He has a routine that gives him a list of words classified by line, and he want the hyphens to be accounted for. So that : "Hello mis- ter world !" gives [(1,["Hello","mister"]),(2,["world","!"])]

Well, that's either a relatively complex hand-written recursion, or you map a predicate that tests for hyphens over the list and zip it with the original, offset by one, and then map it all into the result. -- (c) this sig last receiving data processing entity.
