One new scoop oddly dropped this writer's earnings (6)
I believe the answer is:
income
'earnings' is the definition.
(income from a job)
'one new scoop oddly dropped this writer's' is the wordplay.
'one' becomes 'i' (Roman numeral).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'oddly dropped' indicates alternate letters (letters in odd-numbered positions removed).
'this writer' becomes 'me' (the person who wrote the clues).
The alternate letters of 'scoop' are 'co'.
'i'+'n'+'co'+'me'='INCOME'
(Other definitions for income that I've seen before include "Money gained over time" , "Money from investments or for work" , "What do you make" , "Money coming in" , "Money received on which tax is payable" .)
