Check company books with Rob endlessly (7)
I believe the answer is:
control
'check' is the definition.
(controlling is a kind of checking)
'company books with rob endlessly' is the wordplay.
I cannot really see how this works, but
'company' could be 'co' (abbreviation) and 'co' is found in the answer.
'books' could be 'nt' (abbreviation for New Testament) and 'nt' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for control that I've seen before include "Restraint" , "Keep in line" , "Manage - government" , "Regulate; spymaster" , "domination" .)
