Shot the witches out of Coventry! (3)
I believe the answer is:
try
'shot' is the definition.
(thesaurus)
'the witches out of coventry' is the wordplay.
'the witches' becomes 'coven' (I've seen this in other clues).
'out of' suggests deleting specific letters.
'coventry' with 'coven' taken out is 'TRY'.
(Other definitions for try that I've seen before include "Sample" , "A rugby score, result of effort" , "Make severe demands on" , "Bid" , "A rugby score crossing the line" .)
