Expect AA wit to be sloshed (5)
I believe the answer is:
await
'expect' is the definition.
(synonyms)
'aa wit to be sloshed' is the wordplay.
'to be sloshed' is an anagram indicator.
'aa'+'wit'='aawit'
'aawit' anagrammed gives 'AWAIT'.
(Other definitions for await that I've seen before include "Look out for - expect" , "Look for (future event)" , "Remain in expectation for (an occurrence)" , "Hid a microphone in; bothered" , "Be in expectation of (an event)" .)
