Are all points being taken in by right responder? (8)
I believe the answer is:
answerer
'responder?' is the definition.
('answerer' can be a synonym of 'responder')
'are all points being taken in by right' is the wordplay.
'all points being' becomes 'nswe' (I can't justify this - if you can you should give a lot more credence to this answer).
'taken in by' means one lot of letters goes inside another.
'right' becomes 'r' (common abbreviation).
'are' placed around 'nswe' is 'answere'.
'answere'+'r'='ANSWERER'
Can you help me to learn more?
(Other definitions for answerer that I've seen before include "one responding?" , "Responder to question" .)
