Arrange 70 per cent of security (7)
I believe the answer is:
collate
'arrange' is the definition.
The answer and definition can be both related to thinking as well as being verbs in their base form.
Maybe you can see an association between them that I don't see?
'70 per cent of security' is the wordplay.
I cannot really understand how this works, but
'per' could be 'a' and 'a' is found within the answer.
'cent' could be 'c' and 'c' is present in the answer.
'of' could be 'o' and 'o' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for collate that I've seen before include "Assemble in sequence" , "Arrange (papers)" , "Compare and analyse (two or more sources)" , "Put pages in order" , "Gather and put in order" .)
