A month, we hear, for Miss West (3)
I believe the answer is:
mae
'miss west' is the definition.
(I've seen this in another clue)
'a month we hear' is the wordplay.
'a month' becomes 'M' (standard abbreviation).
'we hear' becomes 'ae' (I am not sure about this - if you are sure you should believe this answer much more).
'm'+'ae'='MAE'
'for' is the link.
Can you help me to learn more?
(Other definitions for mae that I've seen before include "-- West, C-twenty actress" , "- - West, movie vamp" , "Woman" , "The first Hollywood blonde femme fatale, . . . West" , "more Scots" .)
