Odd behaviour of lad after running (6-2)
I believe the answer is:
goings-on
'odd behaviour' is the definition.
'goings on' can be an answer for 'behaviour' (I've seen this before). I am unsure of the 'odd' bit.
'lad after running' is the wordplay.
'lad' becomes 'son'.
'after' is a charade indicator (letters next to each other).
'running' becomes 'going' ('go' can be a synonym of 'run'**).
'son' put after 'going' is 'GOINGS-ON'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for goings-on that I've seen before include "Suspect events or behaviour" , "Suspicious happenings" , "Funny business" , "Activities, esp. dubious ones" , "mischief" .)
