Garland is confident of fun and games (7)
I believe the answer is:
leisure
'fun and games' is the definition.
I can't judge whether this definition defines the answer.
'garland is confident' is the wordplay.
'garland' becomes 'lei' ('lei' can be a synonym of 'garland').
'is confident' becomes 'sure' ('sure' can be similar in meaning to 'confident').
'lei'+'sure'='LEISURE'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for leisure that I've seen before include "Time when not working" , "Use lire (anag)" , "R&R" , "Time to rest and enjoy" , "days off" .)
