Lacking regular income, wife's gone forever (7)
I believe the answer is:
ageless
'lacking regular income wife's gone forever' is the definition.
I can't judge whether this defines the answer.
'lacking regular income wife's gone' is the wordplay.
'lacking regular income' becomes 'wageless' (without a wage).
'wife' becomes 'w'.
'gone' is a deletion indicator.
'wageless' with 'w' removed is 'AGELESS'.
Can you help me to learn more?
(Other definitions for ageless that I've seen before include "Always youthful" , "unaffected by time" , "Ever youthful" , "Lasting forever" , "Perpetually young" .)
