For better morale I eat out (10)
I believe the answer is:
ameliorate
'for better' is the definition.
(to ameliorate is to make better)
'morale i eat out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'morale'+'i'+'eat'='moraleieat'
'moraleieat' with letters rearranged gives 'AMELIORATE'.
(Other definitions for ameliorate that I've seen before include "Make (a bad thing) better" , "Make (something) better" , "seen to improve" , "Become better" .)
