Minister on track after upping business earnings (8)
I believe the answer is:
turnover
'business earnings' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'minister on track after upping' is the wordplay.
'minister' becomes 'rev' (short for reverend).
'track' becomes 'rut' (rut is a kind of track).
'after' says to put letters next to each other.
'upping' is a reversal indicator (I've seen 'up' mean this (in down clue: letters go upwards)).
'rev'+'on'+'rut'='revonrut'
'revonrut' written backwards gives 'TURNOVER'.
Can you help me to learn more?
(Other definitions for turnover that I've seen before include "Tart" , "Quantity of business" , "(Annual) money taken by business; small pie" , "receipts" , "Profit" .)
