Said about half of the population's posts (5)
I believe the answer is:
mails
'posts' is the definition.
(I know this)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Another definition for mails that I've seen is " Sends by post".)
I've seen this clue in The Independent.
Want a hint initially instead of a full solution?
