Absorb totally (7)
I believe the answer is:
engross
'absorb totally' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for engross that I've seen before include "Completely absorb" , "Absorb the attention of (someone)" , "Totally absorb the attention of" , "Absorb, captivate" , "Engulf" .)
