Quote from Echo? (6)
I believe the answer is:
repeat
I believe this clue is a double definition.
'quote' is the first definition.
(thesaurus)
'echo?' is the second definition.
('repeat' can be a synonym of 'echo')
'from' is the link.
(Other definitions for repeat that I've seen before include "Divulge" , "Another chance to see show" , "old movie" , "old TV show" , "Say again, echo" .)
