Content copper let delinquent lead (7)
I believe the answer is:
pleased
'content' is the definition.
(associated in meaning)
'copper let delinquent lead' is the wordplay.
'copper' becomes 'p'.
'let' becomes 'lease' (as in to lease or let a building).
'lead' indicates taking the first letters.
The first letter of 'delinquent' is 'd'.
'p'+'lease'+'d'='PLEASED'
(Other definitions for pleased that I've seen before include "Grateful, delighted" , "Happy, satisfied" , "Gratified" , "like Punch?" , "Glad" .)
