Incorporate or soak up (6)
I believe the answer is:
absorb
I believe this is a double definition.
'incorporate' is the first definition.
(I've seen this in another clue)
'soak up' is the second definition.

(Other definitions for absorb that I've seen before include "Soak up - engross" , "Assimilate or soak up" , "Take in and digest, food or knowledge" , "Assimilate, ingest" , "Occupy the mind fully as good book will" .)
