Alpha females communicate romance (6)
I believe the answer is:
affair
'romance' is the definition.
(I've seen this before)
'alpha females communicate' is the wordplay.
'alpha' becomes 'a' (phonetic alphabet: alpha, bravo, charlie etc.).
'females' becomes 'ff' (I've seen this in other clues).
'communicate' becomes 'air' (I can't explain this - if you can you should believe this answer much more).
'a'+'ff'+'air'='AFFAIR'
Can you help me to learn more?
(Other definitions for affair that I've seen before include "Former Belgian coin" , "Sexual liaison - concern" , "Secret sexual relationship" , "Clandestine romance" , "Raffia (anag)" .)
