Feeble conclusions, we hear, that provide many people with leisure (8)
I believe the answer is:
weekends
'we hear that provide many people with leisure' is the definition.
I can't judge whether this definition defines the answer.
'feeble conclusions' is the wordplay.
'feeble' becomes 'week' (I can't justify this - if you can you should give a lot more credence to this answer).
'conclusions' becomes 'ends' (end is a kind of conclusion).
'week'+'ends'='WEEKENDS'
Can you help me to learn more?
(Other definitions for weekends that I've seen before include "Saturdays and Sundays" , "when SATS are" .)
