Money from Government not good — make violent speech (4)
I believe the answer is:
rant
'speech' is the definition.
(rant is a kind of speech)
'money from government not good make violent' is the wordplay.
I cannot quite understand how this works, but
'not' could be 'nt' (synonyms) and 'nt' is found in the answer.
The remaining letters 'ra' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rant that I've seen before include "Show anger" , "Loud and emotional declamation" , "Shout wildly at length" , "Talk wildly or violently" , "Angry outburst" .)
