Put little work into bad choice (6)
I believe the answer is:
option
'choice' is the definition.
(I know that choice can be written as option)
'put little work into bad' is the wordplay.
'put' means one lot of letters goes inside another.
'little work' becomes 'op' ().
'bad' is an anagram indicator.
'into' with letters rearranged gives 'tion'.
'op' inserted inside 'tion' is 'OPTION'.
(Other definitions for option that I've seen before include "Choice, selection" , "An act of choosing" , "Freedom to choose" , "Potion (anag.)" , "Preference" .)
