Loudly mocking characteristic of half-goat people (7)
I believe the answer is:
satiric
I believe this is a double definition.
'loudly mocking' is the first definition.
'characteristic of half-goat people' is the second definition.
(like a Satyr from Greek mythology)
(Other definitions for satiric that I've seen before include "Using ridicule" , "Relating to sarcastic writing" , "Using mockery" , "with comedic content" , "Cynical" .)
