Married individual mostly looked to get rich (7)
I believe the answer is:
moneyed
'rich' is the definition.
(having money)
'married individual mostly looked' is the wordplay.
'married' becomes 'm'.
'individual' becomes 'one' (an individual is one person).
'mostly' means to remove the first letter.
'looked' becomes 'eyed' (eyeing is a kind of looking).
'eyed' with its initial letter taken off is 'yed'.
'm'+'one'+'yed'='MONEYED'
'to get' acts as a link.
(Other definitions for moneyed that I've seen before include "Well-off" , "Affluent" , "Well-heeled" , "Having means" , "Mo' needy? (Anag)" .)
