Give people your address? (5)
I believe the answer is:
'give' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for orate that I've seen before include "Speak formally" , "Speechify" , "Make a formal speech" , "Talk pompously" , "Erato (anag.)" .)
