Expenses incurred once you leave your front door? (9)
I believe the answer is:
outgoings
'expenses' is the definition.
(I've seen this before)
'incurred once you leave your front door?' is the wordplay.
I cannot quite see how this works, but
'you' could be 'u' (commonly used in online communication) and 'u' is located in the answer.
'leave' could be 'go' (to go is to depart or leave) and 'go' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for outgoings that I've seen before include "Regular expenditure" , "Expenses" , "expeditions" .)
