Turn up with the cash, darling, and that will partly cover you (8)
I believe the answer is:
pullover
'turn up with the cash darling and that will partly cover you' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'turn up with the cash darling' is the wordplay.
'turn' says the letters should be written backwards.
'with' says to put letters next to each other.
'the cash' becomes 'l' (The pound sterling symbol is an elaborate L).
'darling' becomes 'lover' (**).
'up' backwards is 'pu'.
'pu'+'l'+'lover'='PULLOVER'
Can you help me to learn more?
(Other definitions for pullover that I've seen before include "Woolly" , "Jersey" , "Sweater or jumper" , "top gear?" , "Go to side of road" .)
