Business expenses incomprehensible to bosses? (9)
I believe the answer is:
overheads
'business expenses' is the definition.
'overheads' can be an answer for 'expenses' (overhead is a kind of expense). I am unsure of the 'business' bit.
'incomprehensible to bosses?' is the wordplay.
'incomprehensible' becomes 'over' (I can't justify this - if you can you should believe this answer much more).
'to bosses?' becomes 'heads' (I've seen this in another clue).
'over'+'heads'='OVERHEADS'
Can you help me to learn more?
(Other definitions for overheads that I've seen before include "deliveries" , "Costs incurred" , "Expenses involved in running a business" , "projector transparencies" .)
