Crumbling Art Deco villa not right for the good life (2,5,4)
I believe the answer is:
la dolce vita
'the good life' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'crumbling art deco villa not right' is the wordplay.
'crumbling' indicates anagramming the letters.
'not' suggests deleting specific letters.
'right' becomes 'r' (abbreviation).
'art'+'deco'+'villa'='artdecovilla'
'artdecovilla' with 'r' removed is 'atdecovilla'.
'atdecovilla' with letters rearranged gives 'LA DOLCE VITA'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for la dolce vita that I've seen before include "Fellini film about hedonistic lifestyle" , "Nieteen sixty Fellini film" , "bed of roses?" , "The good life (Italian)" , "1960s film by Fellini" .)
