Make something known concerning calf meat (6)
I believe the answer is:
reveal
'make' is the definition.
(thesaurus)
'concerning calf meat' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'calf meat' becomes 'veal' (I've seen this before).
're'+'veal'='REVEAL'
'something known' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for reveal that I've seen before include "Expose or display" , "Make known, expose" , "window, in part" , "Make known, uncover and allow to be seen" , "Leak" .)
