Strangle husband into the drink (5)
I believe the answer is:
choke
'strangle' is the definition.
(I know that strangle can be written as choke)
'husband into the drink' is the wordplay.
'husband' becomes 'h'.
'into' means one lot of letters goes inside another.
'the drink' becomes 'coke' (Coke is an example).
'h' placed into 'coke' is 'CHOKE'.
(Other definitions for choke that I've seen before include "Throttle" , "Constrict the throat" , "Asphyxiate" , "Prevent from breathing" , "Strangle" .)
