Old book you shouldn't have belonging to cop (6)
I believe the answer is:
obtain
'cop' is the definition.
The answer and definition can be both to do with ownership as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'old book you shouldn't have belonging to' is the wordplay.
'old' becomes 'o' (abbreviation).
'book' becomes 'b' (abbreviation for book).
'you shouldn't have' becomes 'ta' (both can mean 'thank you').
'belonging to' becomes 'in' (in can mean being a member of).
'o'+'b'+'ta'+'in'='OBTAIN'
Can you help me to learn more?
(Other definitions for obtain that I've seen before include "Come into possession of" , "Get or lay hold of" , "Hold good" , "Get, procure" , "Get or receive" .)
