Will save us all reviewing overnight phenomenon of The Dreamers - without an intro, it could be for the birds (8)
I believe the answer is:
redeemer
'reviewing overnight phenomenon of the dreamers without an intro it could be for the birds' is the definition.
I can't tell whether this defines the answer.
'will save us all' is the wordplay.
'will' says to put letters next to each other (I've seen this in other clues).
'save' becomes 'redeem' ('redeem' can be a synonym of 'save').
'us all' becomes 'er' (I can't explain this - if you can you should believe this answer much more).
'redeem' put next to 'er' is 'REDEEMER'.
Can you help me to learn more?
(Other definitions for redeemer that I've seen before include "Mere deer for the saviour" , "One who delivers (people) from sin" , "One who saves (sinner)" , "One who saves (another) from sin" , "Christ, who saved us from damnation" .)
