Spit out ends (4)
I believe the answer is:
tips
'ends' is the definition.
(the tips of something are its ends)
'spit out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'spit' anagrammed gives 'TIPS'.
(Other definitions for tips that I've seen before include "extra payments" , "leavings in restaurant?" , "Gratuties" , "Turns over" , "Hints or gratuities" .)
