Spit out hints (4)
I believe the answer is:
tips
'hints' is the definition.
(I know this)
'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 "Turns over" , "Ends" , "Useful hints" , "leavings in restaurant?" , "Hints or gratuities" .)
