Crossword Genius

Ended chief’s expense (8)

Ross

I believe the answer is:

overhead

'expense' is the definition.
(I know that overhead is a type of expense)

'ended chief's' is the wordplay.
'ended' becomes 'over' (synonyms).
'chief' becomes 'head' (synonyms).
'over'+'head'='OVERHEAD'

(Other definitions for overhead that I've seen before include "Aloft" , "An expense in curred in maintaining property" , "Expenses" , "In the sky - type of door or projector" , "Operating cost" .)

I've seen this clue in The Times.
