Take a second job and while away time, getting frivolous? (9)
I believe the answer is:
moonlight
'take a second job and while away' is the definition.
I can't judge whether this definition defines the answer.
'time getting frivolous?' is the wordplay.
'time' becomes 'moon' (I can't justify this - if you can you should believe this answer much more).
'getting' is a charade indicator (letters next to each other).
'frivolous?' becomes 'light' (light can mean trivial or unimportant).
'moon'+'light'='MOONLIGHT'
Can you help me to learn more?
(Other definitions for moonlight that I've seen before include "Reflected illumination" , "Hold a second job" , "Burn the midnight oil" , "Natural (and romantic?) illumination" , "name for sonata" .)
