One escapes pain and hunger in style (7)
I believe the answer is:
panache
'in style' is the definition.
(I've seen this before)
'one escapes pain and hunger' is the wordplay.
'one' becomes 'I' (Roman numeral).
'escapes' is a deletion indicator.
'and' means one lot of letters go next to another.
'hunger' becomes 'ache' (I've seen this in another clue).
'pain' with 'i' taken out is 'pan'.
'pan'+'ache'='PANACHE'
(Other definitions for panache that I've seen before include "Dash and verve" , "Style, elan" , "Brio - flair" , "A dashing manner" , "stylish carriage" .)
