Several points covered in oddly airy response (6)
I believe the answer is:
answer
'response' is the definition.
(answer is a kind of response)
'several points covered in oddly airy' is the wordplay.
'several points' becomes 'nswe' (I can't explain this - if you can you should believe this answer much more).
'covered in' means one lot of letters goes inside another.
'oddly' indicates alternate letters (letters in odd-numbered positions).
The alternate letters of 'airy' are 'ar'.
'nswe' inserted into 'ar' is 'ANSWER'.
Can you help me to learn more?
(Other definitions for answer that I've seen before include "fit" , "Acknowledge" , "Response to a question" , "'Daisy, Daisy, give me your ...... do'" , "Response - solution" .)
