Make disclosures about meat (6)
I believe the answer is:
'make disclosures' is the definition.
'reveal' can be an answer for 'make' (thesaurus). I am not sure about the 'disclosures' bit.
'about meat' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'meat' becomes 'veal' (veal is a kind of meat).
Can you help me to learn more?
(Other definitions for reveal that I've seen before include "Spill beans" , "window, in part" , "Disclose, make apparent" , "Remove cover, unveil" , "Expose or display" .)
