He guides you and me to that woman (5)
I believe the answer is:
'he guides you' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'me to that woman' is the wordplay.
'me' becomes 'us' ('us' can mean 'me' in some dialects).
'to that woman' becomes 'her' (her refers to a woman).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for usher that I've seen before include "Show to seat" , "Doorkeeper; shower to seat" , "Introduce" , "'The Fall of the House of -----', Edgar Allan Poe" , "Person employed to put you in your place" .)
