Had I not gone out to work from choice? (6)
I believe the answer is:
option
'work from choice?' is the definition.
'option' can be an answer for 'choice?' ('option' can be a synonym of 'choice'). I am unsure of the 'work from' bit.
'had i not gone out' is the wordplay.
'had' becomes 'op' (I can't justify this - if you can you should believe this answer much more).
'gone out' is an anagram indicator.
'i'+'not'='inot'
'inot' anagrammed gives 'tion'.
'op'+'tion'='OPTION'
'to' is the link.
Can you help me to learn more?
(Other definitions for option that I've seen before include "Possible choice" , "The choice of taking or leaving" , "Something choosable" , "Right to choose" , "Freedom to choose" .)
