Post-lunch get a paper, nobody around to hamper reading (9)
I believe the answer is:
afternoon
'a paper nobody around to hamper reading' is the definition.
I can't tell whether this defines the answer.
'post-lunch' is the wordplay.
'post' becomes 'after' (the prefix 'post-' means 'after').
'lunch' becomes 'noon' (I can't explain this - if you can you should give a lot more credence to this answer).
'after'+'noon'='AFTERNOON'
'get' is the link.
Can you help me to learn more?
(Other definitions for afternoon that I've seen before include "Time of day" , "No ante for this part of the day" , "one not far out" , "Post-midday" , "several hours" .)
