Make sense of reporting to base (10)
I believe the answer is:
understand
'make sense of' is the definition.
(I've seen this before)
'reporting to base' is the wordplay.
'reporting to' becomes 'under'.
'base' becomes 'stand' ('stand' can be a synonym of 'base').
'under'+'stand'='UNDERSTAND'
(Other definitions for understand that I've seen before include "Comprehend" , "Perceive the meaning of" , "Grasp - sympathise" , "See" , "Get the message" .)
