Discuss how wrongly I get no tea (9)
I believe the answer is:
negotiate
'discuss' is the definition.
(I know that negotiate is a type of discuss)
'wrongly i get no tea' is the wordplay.
'wrongly' is an anagram indicator (I've seen this in other clues).
'i'+'get'+'no'+'tea'='igetnotea'
'igetnotea' with letters rearranged gives 'NEGOTIATE'.
'how' is the link.
(Other definitions for negotiate that I've seen before include "Discuss the terms of an arrangement" , "as diplomat does" , "Bring about by mutual agreement" , "treat! Yes!" , "Deal, bargain" .)
