Introduce us to that woman (5)
I believe the answer is:
usher
'introduce' is the definition.
(I've seen this in another clue)
'us to that woman' is the wordplay.
'to that woman' becomes 'her' (her refers to a woman).
'us'+'her'='USHER'
(Other definitions for usher that I've seen before include "Guide at wedding" , "Doorkeeper in parliament or 29 down" , "R and B star" , "Show to seat" , "Theatre attendant" .)
