Give address that's fancy, not new (5)
I believe the answer is:
orate
'give address that's fancy' is the definition.
I can't judge whether this definition defines the answer.
'not new' is the wordplay.
'not' becomes 'o' (I've seen this in other clues).
'new' becomes 'rate' (I can't justify this - if you can you should believe this answer much more).
'o'+'rate'='ORATE'
Can you help me to learn more?
(Other definitions for orate that I've seen before include "Harangue" , "Speak pompously and at length" , "Lecture" , "Make a formal speech" , "Spout" .)
