Book Alfa Romeo battery recharge (6)
I believe the answer is:
arrest
'recharge' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'book alfa romeo battery' is the wordplay.
I cannot quite see how this works, but
'romeo' could be 'r' (phonetic alphabet: alpha, bravo, charlie etc.) and 'r' is present in the answer.
'battery' could be 'a' (A battery is an example) and 'a' is located in the answer.
The remaining letters 'rest' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for arrest that I've seen before include "Take into custody as police do" , "Seize (a crime suspect)" , "apprehend a law-breaker" , "Sartre (anag) -- check" , "Stop - detain" .)
