Relaxed, being on the road to a comfortable lifestyle (4,6)
I believe the answer is:
easy street
'a comfortable lifestyle' is the definition.
I can't judge whether this definition defines the answer.
'relaxed being on the road' is the wordplay.
'relaxed' becomes 'easy' (associated in meaning).
'being on' is a charade indicator (letters next to each other).
'the road' becomes 'street' (street is a kind of road).
'easy'+'street'='EASY STREET'
'to' is the link.
Can you help me to learn more?
(Other definitions for easy street that I've seen before include "What the postman wants" , "Simple way to achieve financial security" , "Situation of financial comfort or security" , "Place of financial comfort" , "one appreciated by deliveryman?" .)
