Speech giving notice to groom? (7)

I believe the answer is:
address
Here is my best explanation:
'speech' is the definition.
(address is a kind of speech)
'giving notice to groom?' is the subsidiary indication.
'giving' is a charade indicator (letters next to each other).
'notice' becomes 'ad'.
'to groom?' becomes 'dress' (dressing is a kind of grooming**).
'ad' put next to 'dress' is 'address'.
(Other definitions for address that I've seen before include "Discourse", "Speak to the residence", "Give a talk to", "Form of identification for building", "Talk - indication of house", "Place of abode", "Speak to, approach", "Speak to at home?", "Location" and "Where you live".)
