Greedy individual possibly has second meal but no starter (6)
I believe the answer is:
sinner
'greedy individual possibly' is the definition.
I can't judge whether this defines the answer.
'second meal but no starter' is the wordplay.
'second' becomes 's' (common abbreviation).
'meal' becomes 'dinner' (dinner is a kind of meal).
'but no starter' means to remove the first letter.
'dinner' with its initial letter taken off is 'inner'.
's'+'inner'='SINNER'
'has' is the link.
Can you help me to learn more?
(Other definitions for sinner that I've seen before include "One breaking divine law" , "One who breaches the moral law" , "Wrong-doer" , "Miscreant" , "Immoral transgressor" .)
