Expenses for excursions catching game (9)
I believe the answer is:
outgoings
'expenses' is the definition.
(I've seen this before)
'excursions catching game' is the wordplay.
'excursions' becomes 'outings' ('outing' can be a synonym of 'excursion').
'catching' is an insertion indicator.
'game' becomes 'go' (go is a kind of game).
'outings' going around 'go' is 'OUTGOINGS'.
'for' acts as a link.
(Other definitions for outgoings that I've seen before include "Expenses" , "expeditions" , "Regular expenditure" .)
