Not sure what your referring to in this question, but I'll try to answer it for what I think your trying to ask about.
Words make up a major fraction of the overall content that goes into a hubs development. The creation of a hub without words would simply defeat the purpose of hub writing and would get rejected by the system here on hubpages.
With that said all the text you place into the text modules for a hub, will become the necessary required word content that will formulate that acceptable part of a hub.
Hope this answers the question, and please try to be more clear, or add some additional parts to your questioning here in the near future, if you want to get a more accurate response. Thanks for sharing!
