The repast I prepare myself in my leisure hours (5,4)
I believe the answer is:
spare time
'leisure hours' is the definition.
(I've seen this in another clue)
'the repast i prepare myself' is the wordplay.
'prepare' indicates an anagram (I've seen 'preparing' mean this (the same letters prepared differently)).
'myself' becomes 'me'.
'repast'+'i'='repasti'
'repasti' is an anagram of 'spareti'.
'spareti'+'me'='SPARE TIME'
'in my' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for spare time that I've seen before include "Leisure moments" , "leisure hours" , "When we can please ourselves what we do" , "Leisure periods" , "Free period, no commitments (5,4)" .)
