American supporting largely indolent Australian, perhaps reading The Man Who Died Twice (7)
I believe the answer is:
lazarus
'the man who died twice' is the definition.
'Lazarus' can be an answer for 'the man' (I have seen 'Poor man' mean 'lazarus' so perhaps 'man' could also mean 'lazarus'). I'm not certain of the remainder of the definition.
'american supporting largely indolent australian perhaps' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'supporting' says to put letters next to each other (in a down clue, some letters go below others).
'largely' means to remove the last letter (most but not all of the letters).
'indolent' becomes 'lazy' (synonyms).
'australian perhaps' becomes 'rus' (I can't explain this - if you can you should give a lot more credence to this answer).
'lazy' with its final letter taken off is 'laz'.
'a' put after 'laz' is 'laza'.
'laza'+'rus'='LAZARUS'
'reading' is the link.
Can you help me to learn more?
(Other definitions for lazarus that I've seen before include "The man Jesus raised from the dead" , "Brother of Martha and Mary, whom Jesus restored to life" , "Beggar in parable" , "Poor man" , "Brother of Mary and Martha, raised by Jesus from the dead" .)
