Give one's address (5)
'give one's address' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for orate that I've seen before include "make speeches" , "Spout" , "Make a lengthy speech" , "Erato (anag.)" , "Lecture" .)
'address' is the definition.
(synonyms)
'give one's' is the wordplay.
I cannot really understand how this works, but
'one' could be 'a' (a thing is one thing) and 'a' is present in the answer.
The remaining letters 'spek' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for speak that I've seen before include "Talk" , "Utter words" , "give a lecture" , "Orate" , "Say something" .)
