Reveal record will show a deficit (8)
I believe the answer is:
disclose
'reveal' is the definition.
(I know that reveal can be written as disclose)
'record will show a deficit' is the wordplay.
I cannot quite understand how this works, but
'record' could be 'disc' (eg a CD, compact disc) and 'disc' is present in the answer.
The remaining letters 'lose' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for disclose that I've seen before include "Announce" , "Divulge, reveal" , "Betray" , "Make public" , "Is closed in order to expose to view" .)
