Motel menu altered for profit (9)
I believe the answer is:
emolument
'for profit' is the definition.
(I have seen 'Profit of employment' mean 'emolument' so perhaps 'profit' could also mean 'emolument')
'motel menu altered' is the wordplay.
'altered' indicates an anagram.
'motel'+'menu'='motelmenu'
'motelmenu' with letters rearranged gives 'EMOLUMENT'.
(Other definitions for emolument that I've seen before include "profit results" , "Profit of employment" , "Compensation paid" , "A fee received, salary" , "payment" .)
