Young forever lacking regular income? Wife's gone (7)
I believe the answer is:
ageless
'regular income? wife's gone' is the definition.
I can't tell whether this definition defines the answer.
'young forever lacking' is the wordplay.
'young forever' becomes 'age' (I can't explain this - if you can you should believe this answer much more).
'lacking' becomes 'less' (I've seen this in another clue).
'age'+'less'='AGELESS'
Can you help me to learn more?
(Other definitions for ageless that I've seen before include "Never growing old" , "Lasting a long time" , "Never appearing to grow old" , "Sea-legs (anag.)" , "impossible to date" .)
