Drinking a Tango he can’t stand (4)
I believe the answer is:
hate
'can't stand' is the definition.
'drinking a tango he' is the wordplay.
'drinking' indicates putting letters inside.
'a tango' becomes 'T' (phonetic alphabet: alpha, bravo, charlie etc.).
'he' becomes 'hae' (I can't explain this - if you can you should give a lot more credence to this answer).
't' put into 'hae' is 'HATE'.
Can you help me to learn more?
(Other definitions for hate that I've seen before include "Abominate" , "Odium" , "powerful emotion" , "Dislike intensely" , "Despise" .)
