Eros Ltd corrupted senior citizen (7)
I believe the answer is:
oldster
'senior citizen' is the definition.
(I've seen this before)
'eros ltd corrupted' is the wordplay.
'corrupted' indicates anagramming the letters.
'eros'+'ltd'='erosltd'
'erosltd' anagrammed gives 'OLDSTER'.
(Other definitions for oldster that I've seen before include "Person getting on" , "Aged person" , "Senior citizen (colloquial)" , "Greybeard" , "Mature person" .)
