Do without English sweet (7)
I believe the answer is:
execute
'do' is the definition.
(synonyms)
'without english sweet' is the wordplay.
'without' becomes 'ex' (I've seen this in other clues).
'english' becomes 'e' (abbreviation).
'sweet' becomes 'cute' (I've seen this in other clues).
'ex'+'e'+'cute'='EXECUTE'
(Other definitions for execute that I've seen before include "Finish off" , "Carry out, perform" , "Guillotine" , "Carry out or kill legally" , "Carry out; behead" .)
