Distribute, disseminate (6)
I believe the answer is:
spread
I believe this clue is a double definition.
'distribute' is the first definition.
(synonyms)
'disseminate' is the second definition.
(synonyms)
(Other definitions for spread that I've seen before include "American farm" , "expansion?" , "Extent; elaborate meal" , "Stretch out; food paste" , "Generous meal" .)
