Male model to talk about mirror (4)
I believe the answer is:
stag
'male' is the definition.
(a stag is a male deer)
'model to talk about mirror' is the wordplay.
'model' becomes 'T' (Ford Model T car).
'to talk' becomes 'gas' (gas can mean to chat).
'about' indicates putting letters inside.
'mirror' is a reversal indicator (I've seen 'mirrored' mean this).
't' put into 'gas' is 'gats'.
'gats' written backwards gives 'STAG'.
(Other definitions for stag that I've seen before include "Game - speculator" , "Hunted animal" , "Male beast" , "Male at party?" , "Sort of party" .)
