Ace put out vessel (6)
I believe the answer is:
teacup
'vessel' is the definition.
(I've seen this before)
'ace put out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'ace'+'put'='aceput'
'aceput' anagrammed gives 'TEACUP'.
(Other definitions for teacup that I've seen before include "At the end here, maybe, leaves" , "Drinking container that may contain a small storm" , "Scene of unnecessary storm!" , "Small vessel that may contain a storm" , "Drink holder" .)
